CA2332955A1 - System and method for pre-authorization of individual account remote transactions - Google Patents

Abstract

An account processing method and system for providing specific pre-authorization parameters for transactions that require specific pre-authorization by a network user specifying conformity parameters within which any requested transaction parameters must comply in order to enable the requested transaction to be approved. Upon establishment of an account, transaction types by standard industrial code (SIC) are specified as needing specific authorization prior to approving the transaction as requested by a merchant. An account issuer provides a service to account members that permits network user to independently specify the parametric conditions under which to approve a transaction within such categories. Once a transaction is approved, the pre-authorization is spent and requires individual pre-authorization of each transaction, thereby minimizing misuse of an account number by merchants or others that come into possession of the network user's account number.

SYSTEM AND METHOD FOR PRE-AUTHORIZATION OF
INDIVIDUAL ACCOUNT REMOTE TRANSACTIONS

i REhATED APPhI ATIONS
2 This application is a continuation-in-part~of U.S. Patent Application Serial 3 No. 08/957,419 filed October 24, 1997 entitled "System and Method for Pre-4 I Authorization of Individual Account Transactions."
s 1. The Field of the Invention s The present invention relates to electronic authorization of financial transactions, and in particular, to electronic authorization of specific predetermined io transactions. More particularly, the present invention relates to specific ~ s authorization of individual transactions otherwise inhibited or t2 prohibited.

2. Present State of the Art ~s Modernly, more and more transactions in commerce have come to rely upon t6 the convenience of utilizing a transaction card such as a credit card for the purchasing of goods and services. As credit cards have become more ubiquitous, so also has the infrastructure supporting the use of credit cards in commerce.
At one point, what was a simple relationship between a card issuer and a cardholder 2o has evolved to include intermediaries providing authorization services and 2~ financial distribution services. Such an expansive infrastructure has come to 22 facilitate on-line or near real-time transaction authorization.
23 Furthermore, because of the extensive nature of the credit card 2o infrastructure, additional users, not necessarily relying upon credit, also utilize the 2s existing infrastructure in carrying out commerce. For example, businesses or 26 corporations may establish a series of accounts with a card issuer and distribute WO 00/57374 PC'T/US00/07975 t transaction cards to their members for use in executing cashless transactions. To z minimize fraud and abuse in the purchasing of goods and services, authorization 3 standards have been established. Figure 1 represents a standardized authorization process for transaction verification. An account manager, such as a fleet manager s or other entity, desiring cashless transaction privileges contacts a card issuer 114 6 to request the extension of transaction privileges through an established account 7 request I 16. Typically, when establishing a credit account, card issuer 114 places restrictions such as transaction amount limitations upon the card user.
However 9 when establishing accounts for business or other like users,.account manager to may request that card issuer 114 deny certain transactions and strictly enforce other t t ~ limitations on transactions.
t2 Exemplary desired account limitations include restrictions on the types of t3 services and goods that may be procured by an account user 104 as directed by t4 account manager 102. industry standards have been established for the partitioning is of goods and services into categories ~ designated by a standard industrial code t6 (SIC). A merchant 106 is assigned a specific standard industrial code t7 corresponding to their predominate business function. For business transactions is that adhere to the SIC coding, transactions originating at a point of sale terminal t9 having a restricted SIC identifier may be unable to obtain proper authorization to 2o complete a transaction with an account user. Other limitations frequently desired Zt by account managers include transactional limits. Transactional limits may include 22 single transaction limits or aggregate limitations upon successive transactions.
23 Card issuer 114 upon the establishment of an account may employ a third 24 party authorizing agent to provide authorization services and strictly enforce 2s transaction limitations as agreed upon between account manager 102 and card 26 issuer 114. Card issuer 114 through an establish authorization request 118 informs authorizing agent 112 of the transaction terms under which transaction 2 authorization may be granted.
Once an account has been established account manager 102 provides the 4 account information necessary to enable account user 104 to engage in commerce s transactions. Such account information generally includes an account number as assigned by card issuer 114. The predominate form of providing account information to account user 104 is to provide account user 104 with a transaction s card generally taking the form of a credit card-like card be$ring the account number thereon. Account user 104 upon initiating a transaction with a merchant 106 to engages in a payment presentment step 120 by providing the requisite account information to merchant lOb. Merchant 106 engages in an authorization process iz to verify that the transaction parameters of the present transaction are within the' boundaries or limitations placed upon the account as requested by account manager 102 or imposed by card issuei l 14. An authorization request 122 issued ~s by merchant 106 is comprised of an account number, a transaction amount and t6 other parameters such as a standard industrial code (SIC), a merchant identifier t~ (M1D) and an acquiring bank identification number (BIN).
~s A merchant 106 typically associates with an acquiring bank 108 which s9 provides funding services of merchant transactions. Authorization requests may 2o electronically pass through acquiring bank 108 as designated by the BIN of the z~ authorization request and additionally may route through a card company I
10 (e.g., zz MasterCard~, VISA~, Discover Card~ or American Express~) prior to reaching z3 authorizing agent 112 for comparison of account parameters. Authorizing z4 agent 112 compares the transaction parameters for conformance with account 2s limitations. Authorizing agent I12 issues an authorization response 124 2s comprising an acceptance or denial indicator.

t During general authorization processing, funds generally do 'not transfer at that time. A settlement generally occurs at a periodic time such as evenings or 3 nights when a merchant re-initiates communication with an authorizing agent and 4 presents a series of accepted and authorized transactions occurring throughout the s previous period and requests financial settlement of such transactions.
Merchant 106 initiates a settlement request 126 with authorizing agent 112 which generally comprises the account number to be debited, the amount of the debit and s other information such as SIC, MID and BIN designators. As part of the settlement 9 process, authorizing agent 112 issues a settlement request 128 to card issuer 114.
to Frequently a settlement request 128 includes less cryptic merchant information n (i.e., merchant name and city/state address instead of MID) for later presentment i2 to an account manager. Card issuer 114 in a payment settlement response step 130 t3 passes payment information on to merchant's acquiring bank 108 with the to appropriate funds transferring in a step 131.
is At yet another periodic point in time, card issuer 114 provides a billing tb account 132 to account manager 102 for notification of payment due or for other t~ record keeping purposes. Such billing account information may be presented in ~s various forms including printed statements as well as electronic reporting.
In such t9 generic authorization processing as described above, billing account information 2o contains relatively little and non-descriptive information such as an account 2t number, a transaction amount and merchant information.
i2 At least three particular shortcomings of the authorization process as 23 described in Figure 1 should be pointed out. First, authorization performed by 24 authorizing agent 112 provides a regulation of transactions by either proscribing is transactions originating at a merchant having a proscribed SIC
goods/services 26 designator, or withholding authorization from transactions that exceed i transactional limits. Such an authorization process approves transactions of values 2 less than the transactional limits transpiring at non-proscribed merchant point of sale terminals having a non-barred SIC goods/services designator. Prior art 4 authorization techniques do not provide a method or system for enforcing strict s transaction parameters prior to authorization of restricted transaction types on a 6 transaction by transaction basis. Additionally, prior art techniques do not permit an account manager to create transaction authorization parameters without re-s initiating account establishment procedures.
A second shortcoming of the authorization processing in the prior art to relates to billing account information sent from card issuer 114 for evaluation by tt account manger 102. As shown in Figure 1, the billing account information is ~2 comprised of an account number and an amount coupled to merchant information ~3 ~ such as the name and city of the merchant. An account manager does not have a t4 tracking mechanism to track the execution of a specific transaction and the billing is of such a transaction on a billing statement if the vendor and acquiring hank cannot is provide this functionality. In prior art configurations, the account manager only m discerns that a certain amount of money, a transaction amount, was exchanged with a specific merchant.
Other transaction systems have incorporated item descriptions generally Z0 ascertainable from SKU numbers listing goods or services obtained from the listed merchant into their billing statements. 1t should be noted that such techniques still z2 do not provide a tracking mechanism for linking a specific authorization procedure 23 to a billing account printout.
24 A third short coming of the authorization processing in the prior art relates 2s to the inability to prevent fraudulent successive transactions using the account 26 number of an account user once it has been divulged to a merchant. In many t instances and applications, transactions are performed remotely from the physical 2 presence of the account user thereby foreclosing the account user from discretionary evaluation of the credibilityof the merchant with which an account 4 user's account number would be divulged. In such an application, the rogue s merchant would be free to utilize the account number in successive authorization requests and alternatively could resell or post an account user's account number for 7 indiscriminate use by other devious entities. Because such an opportunity exists s such as in the case of remote network and chiefly Internet purchasing environments, account users have theretofore been hesitant to engage in electronic io commerce using a credit or other form of transaction card or vehicle that exposes > > an account user's account number into an environment whose security is at best .~2 suspect.
t3 . Accordingly, what is needed is a method and system for authorizing in i4 advance or pre-authorizing transactions that but for specific authorization, are ~s otherwise proscribed.
What is also needed is a method and system for enforcing parameters upon such pre-authorized transactions such as transaction amounts, specific merchants and other transaction related parameters.
Also, what is yet needed, is a method and system for facilitating an audit 20 or record reconciliation from a pre-authorized transaction through the billing of the 2~ account thus informing an account manager of the completion of a pre-authorized 22 transaction.

SUMMARY AND OBJEST~(,~F TH ~ lrtv~nITION
2 It is an object of the present invention to provide a method for authorizing an account when a portion of the account transactions require individual pre-authorization according to specified pre-authorization parameters.
s It is another object of the present invention to provide a system for authorizing an account when a portion of the account transactions require individual pre-authorization according to specified pre-authorization parameters.
It is a further object of the present invention to provide a method for authorizing a portion of account transactions otherwise denied by requiring to individual pre-authorization according to parameters pre-authorized in a pre t t authorization process.
t2 It is yet another object of the present invention to provide a method and t3 system for associating a transaction identifier within a pre-authorization process to such that upon the completion of the transaction, the associated transaction is identifier follows the transaction information through the billing account phase, t6 thus allowing reconciliation of a specific transaction from a previously assigned transaction identifier.
t8 It is still yet another object of the present invention to provide a method and t9 system for authorizing all account transactions which without such pre-2o authorization would otherwise be denied in wholesale. Such a method and system 2t enforces a collateral pre-authorization of each and every transaction in order to 22 approve or accept an authorization transaction initiated by a merchant entity.
Additional objects and advantages of the invention will be set forth in the 2a description which follows, and in part will be obvious from the description, or may 2s be learned by the practice of the invention. The objects and advantages of the i invention may be realized and obtained by means of the instruments . and z combinations particularly pointed out in the appended claims.
To achieve the foregoing objects, and in accordance with the invention as embodied and broadly described herein, an account processing method and system s ~ for facilitating the general denial of all or specific categories of transactions unless 6 they are specifically pre-authorized with specified parameters and the parameters of the requested transaction conform to those pre-authorized parameters is provided. Additionally, the present invention provides a system and method for the 9 pre-authorization of specific transactions to be performed by an account manager io via a service provided by an account issuer to their customers such as account t t managers and users.
~2 A further advancement of the present invention provides a method and ~3 system for allowing an account manager to define a transaction identifier (e.g.~, ~4 insurance claim number, purchase order. number, work order number, etc.) and is attach the transaction identifier through a pre-authorization of a transaction. Upon the initiation and authorization of a requested transaction conforming to the t7 specified pre-authorization parameters, the transaction identifier is included with ~s the generic billing information (e.g., transaction amount, merchant information, etc.) thus allowing an account manager to reconcile their accounting from a billing 2o account information containing the transaction having the transaction identifier 2t associated thereto with a pre-transaction assignment of a traditional identifier such 22 as purchase order number, work order number, or insurance claim number.
23 The above described system and method includes an account establishment z4 phase of an account process wherein an account manager approaches a card 2s issuer to establish an account in an establish account step. During the 26 establishment of an account, limitations on transactions relating to that account are negotiated between the account manager and card issuer. Transaction limitations 2 generally include items such as transaction limits, account balance limit, limitations on categories of goods or services as denoted by standard industrial 4 codes (SIC) and other parameters that may be incorporated into a specific s accounting scheme. In an alternate embodiment, a system and method is described wherein a consumer-to-business transaction environment, the account user personally initiates the account establishment phase with the card issuer.
In the present invention, upon the establishment of an account or during the amending or changing of an account, transactions involving certain categories of ~o goods or services as denoted by pre-authorization SICs that denote categories of goods or services, have individual parametric constraints placed upon them. A
card issuer employs the services of an authorizing agent for performing account t3 authorization upon the initiation of a transaction request from a merchant.
The t4 card issuer, in an establish authorization step, forwards various parameters such as ~s SIC limits that wholly bar categories of transactions, transaction limits relating to non-pre-authorization transactions and pre-authorization SICs designating categories of goods or services requiring specific authorization in conformance ~s with pre-authorization parameters subsequently dispatched to the designated authorizing agent in a pre-authorization process.
2o In the present invention, once an account is established with a card issuer, 2~ an account manager may perform pre-authorization of transactions with the card 22 issuer directly. In the preferred embodiment, an account manager using a 23 communication device such as a personal computer may routinely generate pre-24 authorization requests by transferring pre-authorization parameters to the card 2s issuer via communication channel such as the INTERNET. In an alternate 26 embodiment such as a consumer-to-business environment, the account user may a personally perform the transaction pre-authorization directly with the card issuer.
Z In a remote or networking-type environment, the account user may pre-authorize 3 the transaction by employing a network such as the INTERNET which enables the 4 account user to interface with the card issuer through a card issuer's interactive s interface such a web page.
A typical scenario wherein the present invention is practiced provides for z a pre-authorization transaction phase that commences with a request by an account 8 user for a specified good or service that requires pre-authorization prior to initiating the transaction. The account user consults with the account manager for to requesting restricted goods or services. The account manager in turn contacts the t t merchant for negotiating or obtaining a price quotation for the requested goods or t2 services, or optionally; the account manager arrives at a quotation amount by t3 consulting other traditional pricing sources such as directories or catalogs.
t4 . The account manager issues a pre-authorization request to the card issuer is via a personal computer. The account manager in the pre-authorization is request specifies an account number for which pre-authorization transaction parameters apply. In the preferred embodiment, one or more transaction t8 parameters including a quote amount resulting from the quotation process, an t9 acceptable variance or deviation range from the quotation amount, a merchant 2o identifier (MID) or an acquiring bank identification number (BIN) are dispatched 2t to the card issuer. It should be pointed out that in the present invention, one or 22 more of the pre-authorization parameters tray be specified while others may not be 23 specified thus permitting the spectrum of possible options for such criteria. The 2e card issuer relays the pre-authorization parameters to the authorizing agent for 2s storage and usage during authorization processing. In an alternate consumer-to-26 merchant environment, the account user assumes the role of the account manager , . WO 00/57374 PCT/US00/07975 by both seeking out the goods or services to be procured and additionally by pre-2 authorizing or approving a future transaction that undergoes a merchant 3 authorization request.
4 Another aspect of the present invention includes the ability to input or s provide a transaction identifier for association with an authorized completed 6 transaction. The transaction identifier, in the preferred embodiment, provides an 7 alpha-numeric field wherein an identifier may be specified and associated with a s pre-authorized transaction and upon the initiation and authorization of the 9 requested transaction, the transaction identifier is reported .in the billing account information. Such a transaction identifier eaables an account manager to associate a pre-authorization of a transaction with a transaction reported in a billing account ~2 thereby allowing reconciliation of accounting entries.
. The, pre-authorization parameter record remains within the authorizing ~o agent until a matching transaction is initiated~by an account user. When an account n user initiates a transaction for goods or services, a merchant initiates an authorization request for approval. In the present invention, the authorization t7 request takes the form of presentment of a transaction card or other credit card-like as credentials bearing an account number as previously assigned for use by the t9 account user. An account user or account manager may present the account number zo to the merchant using means other than a transaction card such as the presentment, 2~ verbal disclosure, electronic disclosure or written disclosure of an account number a to the merchant.
23 During the authorization, the merchant forwards the account number, the 24 transaction amount, and alternatively other information such as the merchant's SIC
2s denoting its category of goods or services, the merchant's MID and the acquiring 26 HIN associated with the merchant. The authorizing agent performs the i authorization process which includes consulting the pre-authorization table when z the merchant SIC presented in the authorization request corresponds to a pre-3 authorization SIC presented during the establishment of the account. The 4 authorizing agent issues an authorization response listing the acceptance or denial s status resulting from the authorization process.
6 During the settlement of the account, generally at the end of the business day, the merchant forwards the account numbers, the transaction amounts and other s pertinent and related information such as the merchant's SIC and city location 9 relating to each of the authorized transactions for the day. In one embodiment of to the present invention, the authorizing agent additionally forwards the transaction t t identifier as received in the pre-authorization request. In the billing account issued t2 by the account issuer to the account manager, the billing account includes details t3 of the account number, the transaction amount, merchant information and when t4 present the transaction identifier. By presenting the transaction identifier to the is account manager, transactions authorized in''the pre-authorize transaction phase tb may be traced through the authorization, settlement and reporting phases of account t~ processing. By tracing or having a designator assigned to a specific transaction, to the accounting resources of the account manager may close out such transactions t9 upon reporting the completion of the transaction.
20 In a networked consumer user-to-merchant environment, such as in an 2t electronic commerce environment, the individual pre-authorization of each 22 transaction by a user prior to the actual payment presentment activity, minimizes 23 the fraudulent use of an account user's account number when divulged during a 2a payment presentment step. Such misuse is curbed due to the fact that any 2s subsequent authorization requests by a merchant or unauthorized user would be 26 denied since the account user would not have individually pre-authorized each and t every transaction attempted by the user rogue merchant thereby denying subsequent 2 debits against the account user's account.
3 These and other objects and features of the present invention will become 4 more fully apparent from the following description and appended claims, or may s be learned by the practice of the invention as set forth hereinafter.

tt It should also be appreciated that the functions of the "bank card t2 association," "authorizing agent," "card issuer," and the sponsor of an t3 "authorization web page" may be one or several entities providing a combination t4 of these functions. -ts As described in the Background of the Invention, Figure 1 is a flow diagram is of an authorization process in accordance with the prior art.
Figure 2 is a flow diagram of account processing incorporating pre-ss authorization of individual transactions or transaction types, in accordance with a t9 preferred embodiment of the present invention. As account processing has become 2o increasingly prevalent and sophisticated, the complexities of account processing 2t have also increased. For example, in the establishment and processing of an 22 account, additional specified participants are incorporated into the processing flow.
23 In one preferred embodiment, during an account establishment phase of an account 2a process, an account manager 202 approaches a card issuer 214 to establish an zs account as represented in Figure 2 by establish account step 216. During the 26 establishment of an account, limitations on transactions relating to that account are i negotiated between account manager 202 and card issuer 214. Transaction 2 limitations generally include items such as transaction limits, account balance 3 limit, limitations on categories of goods or services as denoted by standard a industrial codes (SIC) and other parameters that may be incorporated into a specific s account scheme.
6 1n the present embodiment of the invention, upon the establishment of an account or during the amending or changing of an account, transactions involving certain categories of goods or services as denoted by pre-authorization SICs denote goods or services that require individual parametric constraints upon such to transactions. For example, account manager 202 may establish an account for use tt by an account user 204 for performing maintenance upon a fleet vehicle. In order t2 to police the use of the account for limited maintenance purposes, account t3 manager 202 designates the SIC associated with maintenance as a pre-authorization t4 SIC requiring conformity to transaction parameters subsequently defined by is account manager 202.
t6 Card issuer 214 employs the services of an authorizing agent 212 for performing account authorization upon the initiation of a transaction request from ttt a merchant. Card issuer 214 in establish authorization step 218 forwards SIC limits t9 controlling categories of transactions, transaction limits relating to non-pre 2o authorization transactions and pre-authorization SICs designating categories of 2t goods or services requiring specific authorization according to pre-authorization 22 parameters subsequently dispatched to authorizing agent 212.
23 In the present invention, once an account is established with a card issuer, 24 account manager 202 may perform pre-authorization of transactions with card 2s issuer 214 directly. In the preferred embodiment, account manager 202 using a 2s personal computer may routinely generate pre-authorization requests by i transferring pre-authorization parameters to card issuer 214 via the INTERNET.
A pre-authorization transaction phase commences with a request 220 by an 3 account user 204 for a specified good or service that requires pre-authorization 4 prior to initiating the transaction. Account user 204 consults with account s manager 202 to obtain restricted goods or services. Account manager 202 in turn 6 contacts a merchant 206 for negotiating or obtaining a price quotation 222, including a quote amount for the requested goods or services. Optionally, account s manager 202 may consult a price quotation directory or catalog containing price 9 quotations for goods or services as requested by account user 204. In yet another to option, account manager 202 may independently generate or approximate a quote t t amount for a requested goods or service for use in the pre-authorization process.
t2 Account manager 202 issues a pre-authorization request 224 to card t3 issuer 214, in the preferred embodiment, using a personal computer that is to electronically coupled to card issuer 214. Account manager 202 in pre-ss authorization request 224 specifies an account number for which pre-authorization t6 transaction parameters apply. In the preferred embodiment, one or more m transaction parameters including a quote amount resulting from the quotation is process, an acceptable variance, or deviation range from the quotation amount, a t9 merchant identifier (MID) and an acquiring bank identification number (BIN) are 2o dispatched to card issuer 214. It should be pointed out that in the present 2i invention, one or more of the pre-authorization parameters may be specified while ii others may not be specified, thus permitting the spectrum of possible options for z3 such criteria. For example, account manager 202 may specify a quote amount and 24 a variance or deviation from the quote amount, such as in the case permitting the 2s inclusion of sales tax with the quoted transaction amount, while leaving the 26 merchant identifier and acquiring bank identification number unspecified, thereby .

t permitting an account user to seek out the goods or services of any merchant for processing the requested transaction.
3 Another field that may be input or provided by account manager 202 is a 4 transaction identifier field. The transaction identifier, in the preferred s embodiment, provides an alpha-numeric field wherein an identif er may be 6 associated with a pre-authorized transaction and upon the initiation and authorization of the requested transaction, the transaction identifier is reported in s the billing account information. Such a transaction identifier enables an account manager to associate a pre-authorization of a transaction with a transaction to reported in a billing account thereby allowing reconciliation of accounting entries.
t t Referring to Figure 2, card issuer 214 employs its established relationship t2 with authorizing agent 212 to forward a pre-authorization request 226 comprised t3 of the account number and other transaction parameters which may optionally include a transaction identifier. Authorizing agent 212 retains and stores the pre-ss authorization transaction parameters in a pre-authorization table 318 (Figure 3) for t6 subsequent authorization when a transaction presents an SIC corresponding to one t7 designated as a pre-authorization SIC.
is The pre-authorization parameter records remain within authorizing t9 agent 212 until a matching transaction is initiated by an account user.
Optionally, 2o pre-authorization parameters may become stale and expire if not timely used.
2t Account user 204 requests goods or services from merchant 206 and thereafter 22 initiates a payment presentment 228 for reimbursement to merchant 206. In the 23 preferred embodiment, payment presentment 228 takes the forth of presentment of 24 a transaction card or other credit card-like credentials bearing an account number 2s as previously assigned for use by account user 204. It should be noted that the 26 present invention does not require account user 204 to present tangible credentials t bearing an account number, but also accommodates the presentment of an account 2 number to a merchant in intangible form, such as the recitation of an account 3 number to merchant 206 for discrete key entry by merchant 206 at the 4 commencement of the authorization process.
s In yet another embodiment as detailed in Figure 6, account manager 202 (Figure 2) rather than account user 204 (Figure 2) divulges an account number for use by merchant 206 (Figure 2) upon the rendering of goods or services. Such a s process has application to businesses such as the insurance industry wherein 9 account manager 202 may play the rote of a claims adjuster disclosing an account to number to merchant 206 for payment of services rendered for an insurance claim.
t t Returning to a discussion of the embodiment depicted in Figure 2, t2 merchant 206 upon receipt of the account number iwformation verifies the status t3 and acceptance parameters of the present account by performing an authorization to request 230 with authorizing agent 212. Merchant 206 forwards the account is number, transaction amount, the merchant's SIC denoting its category of goods or 16 services, the merchant's MID and the acquiring BIN associated with merchant 206.
» Authorizing agent 212 performs the authorization process which includes is consulting the pre-authorization table when the merchant SIC presented in t9 authorization request 230 corresponds to a pre-authorization SIC presented in 2o establish authorization step 218. The authorization process of authorizing 2t agent 212 is detailed in the flowchart of Figure 4. At the conclusion of the 22 authorization process, authorizing agent 212 issues an authorization response 232 23 listing the acceptance or denial status resulting from the authorization process to 24 merchant 206.
2s Generally at the authorization phase of a transaction, funds do not transfer 26 between the parties. Rather, a settle account phase generally occurs at a periodic t point in time such as at the end of a business day or week. At such time, z merchant 206 compiles a complete listing of authorized transactions occurring 3 within the specified period which includes the present transaction of the previous a discussion, and initiates a settlement request 234 with authorizing agent 212 by s divulging the account number, the transaction amount and other pertinent and related information such as the merchant's SIC, MID and BIN.
In some financial configurations, authorizing agent 2I2 may also act as an s account clearinghouse providing account settlements for card issuers having an 9 established relationship with authorizing agent 212. Authorizing agent 212 issues to a settlement request 236 to card issuer 214 which may contain the same or similar t t information as received from settlement request 234 or as shown in settlement t2 request 236 may contain more descriptive information such as a merchant name and n city as opposed to an MID. In one embodiment of the present invention, to authorizing agent 212 additionally forwards the transaction identifier as received is in pre-authorization request 226. Card issuer 214 issues payment settlement t6 response 238 to acquiring bank 208 with the subsequent settlement response for settlement of the account resulting from the present transaction.
is Card issuer 214 issues a billing account 240 to account manager 202 t9 detailing the account number, the transaction amount, merchant information and, 2o when present, the transaction identifier. By presenting the transaction identifier 2t to account manager 202 transactions authorized in the pre-authorize transaction 22 phase may be traced through the authorization, settlement and reporting phases of 23 account processing. By tracing or having a designator assigned to a specific 24 transaction, the accounting resources of account manager 202 may close out such Zs transactions upon the reporting of the completion of the transaction.

t Figure 3 is a simplified diagram of authorization tables employed by an 2 authorizing agent for use in comparison of parameters of a requested transaction 3 with authorization limitations placed upon transaction, in accordance with an 4 embodiment of the present invention. An authorization agent 212 (Figure 2) stores s therein an authorization table 300 containing parameter lirriitations as previously 6 designated during the establish account phase of an account processing procedure.
7 During a traditional authorization procedure, the authorizing agent references a a standard authorization table containing limitations such as an SIC limit 312, a 9 transaction limit 314 and a balance limit 316. In the present invention specified to categories of transactions may be allowed to proceed when a prc-authorization tt process . has taken place. Such transaction categories are stored within t2 authorization table 300 in a pre-authorization SIC table 302.
t3 . As illustrated in Figure 3, SICs 304, 306 :and 308 correspond to SIC
t4 category codes X, Y and Z, respectively, and designate transaction categories is requiring consultation with a pre-authorization table 318 to determine the t6 authorization of a requested transaction. In the preferred embodiment, pre-» authorization table 318 is comprised of a series of fields designating transaction is parameters that must be in compliance prior to issuing an authorization of the t9 requested transaction. Such transaction parameters include a quote amount 322, 2o a vaiiance 324, a merchant ID (MID) 326 and an acquiring bank identification 2t number (BIN) 328. Quote amount 322 is comprised of an upper price boundary for 22 an approved transaction. A variance parameter 324 optionally provides tolerance 23 values for accommodating variations in "amounts." For example, a variance may 24 typically take the form of sales tax or regionalized price fluctuations or other 2s variations. Merchant identifier 326 optionally may provide a parameter requiring 26 the transaction to originate from a designated merchant or point of sale location.

. WO 00/57374 PCT/US00/07975 t Furthermore, acquiring bank identification number 328 may optionally provide a further grouping of select merchants and employ a specified bank before authorizing the transaction in question.
4 In another embodiment, a transaction identifier 330 is associated with pre-s authorization transaction parameters during the pre-authorization process.
Such 6 association of an identifier permits a pre-authorizing agent such as an account manager to specify a purchase order number, a work order number or an insurance s claim number to be included within the pre-authorization parameters of such goods 9 or such services. Following the initiation and authorization of a transaction to wherein the pre-authorization parameters were matched, the transaction identifier t t is attached. with the settlement request information, depicted as settlement tz request 236 (Figure 2), for conveying the transaction information to a card issuer t3 for reconveyance to the account manager. Upon receipt of the transaction identifier associated~::with the completed transaction account manager 202 may rectify is accounting books or other records referencing the transaction identifrer because the t6 transaction identifier was associated with the billing account and request for payment. Such a technique enables a merchant to receive payment almost is immediately upon the dispatch of a settlement request and relieves the t9 accompanying correspondence associated with "cutting" a purchase order and 2o writing a check for accounts payable.
Zt In an alternate embodiment of the present invention, pre-authorization 22 table 318 further comprises an SIC identifier field 320 for associating with a 23 specific set of pre-authorization parameters. Furthermore, each parameter within 24 the pre-authorization table need not be specified allowing greater flexibility to an 2s account user in selecting vendors of goods or services.

wo oois~3~a pc~r~rsooio~9~s t Figure 4 is a flowchart of an authorization process incorporating pre-2 authorization, in accordance with a preferred embodiment of the present invention.
An authorizing agent pre-authorization verification process 402 is carried out within an authorizing agent such as authorizing agent 212 described in Figure 2.
3 Although the previous discussions including Figure 2 have illustrated entities such as authorizing agents being separate from card issuers, nothing prevents the combination of these elements into a single entity carrying out both processes 8 therein. ' For example an account manager 202 (Figure 2) and account user (Figure 2) may easily be combined into a single entity that both manages and uses to an established account. Additionally, acquiring banks and card companies may t t further be included within other entities such as a card. issuer or authorizing agent.
t2 Authorizing agent pre-authorization verification process 402, in the t3 preferred embodiment, is carried out by an authorizing agent 212 (Figure 2) by t4 consulting a pre-authorization's SIC table 302 (Figure 3). of authorization table 300.
is A query task 404 compares the SIC value of the requested transaction with those t6 previously stored within the pre-authorization SIC table 302 (Figure 3) during the establishment of the account phase. When the SIC code of the requested is transaction dots not match a SIC code specifically requiring additional pre-t9 authorization, a standard authorization processing task 406 occurs wherein the 2o standard authorization table 310 (Figure 3) having specific limitations such as 2t transaction or balance limits is performed.
z2 When query task 404 determines that the SIC code of the requested 23 transaction corresponds with a SIC code requiring pre-authorization, a query 24 task 408 performs a cursory evaluation upon the pre-authorization table to 2s determine if there is a pre-authorization entry present. When a pre-authorization i6 . WO 00/57374 PCT/US00/07975 entry is not present, a deny transaction task 410 returns a deny transaction status 2 in the authorization response 232 (Figure 2).
3 When query task 408 locates pre-authorization data within the pre-4 authorization table, a query task 412 evaluates the requested transaction amount s against the quote amount including any variance parameters included within the 6 pre-authorization table. When the requested transaction amount exceeds the quote amount including any variances, the requested transaction is denied as described s above. When the requested transaction amount does not exceed the boundaries established by the quote amount including any variances, a query task 414 further to evaluates any other specified parameters such as merchant ID (M1D) or acquiring t t bank identification number (BIN) against those supplied by the requested t2 transaction: Again, if the parameters of the requested.transaction do not conform t3 o.f those specified in the pre-authorization table, the transaction is denied.
t4 When query task 414 determines that the parameters of the requested is transaction conform to all other parameters specified in the pre-authorization table, is an approved transaction task 416 authorizes the transaction in the affirmative.
Although the above flow diagram has been specified in terms of task ordering, is nothing precludes the evaluation of parameters or conditions in varying orders. For t9 example, a merchant identifier specified in the pre-authorization table may be 2o compared primary to the evaluation of the transaction amount without affecting the 2t spirit of the invention.
22 Figure 5 is a depiction of a billing account report associating a transaction z3 identifier with a transaction yet to be billed, in accordance with an embodiment of 24 the present invention. As discussed above, a transaction identifier 510 may be is associated to a pre-authorized transaction generated by an account manager.
26 Traditional billing statements presented to an account manager contain generic t information such as an account number, a transaction amount and information 2 identifying a merchant. Historically, an account manager was then left to search 3 back through claims, work orders or purchase orders to align a transaction amount a and merchant identifier contained within the billing statement to an earlier s authorization.
In the present invention, a billing account 502 is comprised of an account number 504, merchant information 506, a transaction amount 508 and a transaction a identifier 510. Transactioa identifier 510, by containing descriptive information unique to the transaction, enables an account manager to quickly identify a to corresponding authorization document for account reconciliation. In the preferred embodiment of the present invention, transaction identifier 510 contains an alpha t2 numeric field which is defined by account manager 202 (Figure 202) and ~3 distributed to.card issuer 214 using pre-authorization request 224, which in turn is t4 forwarded to authorizing agent 212 and pre-authorization request 226, respectively.
is By allowing a transaction identifier to be associated with pre-authorization process, t6 less sophisticated equipment such as transaction processing equipment resident at a merchant point of safe may remain relatively unsophisticated as such equipment does not process or pass through any additional parameters such as a transaction t9 identifier but the account manager still gets a unique per transaction identification 2o code.
2t Figure 6 is a flow diagram illustrating account processing which employs 2s pre-authorization of select transactions without requiring an account user to 23 perform a payment presentment step, in accordance with an embodiment with the 24 present invention. In the present embodiment, the established account phase 2s proceeds according to that of the previous embodiment wherein an established 26 account 616 and an established authorization step 618 establish an account number, ~ WO 00/57374 PCT/US00/07975 SIC limitations, transaction limitations and pre-authorization SICs requiring individual pre-authorization.
3 An account user 604 requests goods or services of an account manager 602 4 in a task 620. Account manager 602 negotiates a price quotation 622 from a s merchant 606. Account manager 602 either upon resolution of a price quotation 6 from a merchant 602 or, as discussed above, account manager 602 may obtain a quote amount value for placing within a pre-authorization request from other s sources such as other standard pricing materials.
In the present embodiment, account manager 602 provides merchant 606 as opposed to account user 604 with an account number in account disclosure step for utilization in a subsequcat authorization request initiated by merchant 606.
~z Following the disclosure of the account number to : merchant 606, account n manager 602 '.performs a pre-authorization request 62G -in accordance with the t4 description of the previous embodiment. A pre-authorization request 628 then is flows from card issuer 614 to authorizing agent 612 for population of the pre~
tb authorization table 318 (Figure 3). Such steps complete the pre-authorization i7 phase of the account processing procedure.
is Upon the rendering of service or delivery of goods, merchant 606 commences an authorization transaction process by issuing an authorization 2o request 630 to authorizing agent 6I2 utilizing the account number delivered thereto 2i by account manager 602 in account disclosure steps 624. Such an account number 22 distribution technique is useful for applications such as insurance claim processing.
23 For example, account user 604 assumes the role of an insured placing a claim 24 against account manager 602, who further assumes the role of the insurer, or 2s alternatively, a claims adjuster. Account manger 602 negotiates a repair price with 26 a merchant 606 assuming the role, in the case of auto insurance, of a repair shop.

t Upon completion of the negotiation process and the resolution of a claim Z amount, account manager 602 (i.e., claims adjuster) discloses an account number 3 for use by merchant 606 (i.e., repair shop) for use in obtaining reimbursement for 4 goods and services upon the completion of rendering such goods or services.
s Account manager 602 (i.e., claims adjuster) initiates pre-authorization request 626 by including the divulged account number, and any other parameters deemed necessary (e.g., merchant identification number). Furthermore, to aid account s manager 602 (i.e., claims adjuster) in reconciling their accounting system, account manager 602 includes a transaction identifier, which by way of example may be in so the form of an insurance claim number uniquely identifying the requested claim by theinsured.
~2 Upon the rendering of services or the delivery of=goods, merchant 606 {i.e., t3 repair shop.) issues an authorization request 630 comprising the account number disclosed with the amount of the transaction and other identifiers flowing ~s therewith. Authorizing agent 612 performs an authorization procedure and renders an authorization response 632 stating the status of either acceptance or denial of t~ the requested transaction to merchant 606. Merchant 606, at a periodic interval, issues a settlement request 634 containing the account number, transaction amount and other identifying fields to authorizing agent 612 for account reconciliation.
2o Authorizing agent 6I2 processes the settlement request in conjunction with card zt issuer 614 in a settlement request 636 including the account and transaction-related zz information such as account number, transaction amount, merchant Zs number/name/address and the transaction identifier tieing the present billing line 2a item to the originating claim number as delivered to account manger 602 in billing 2s account step 640 as further received from settlement request step 636, and 26 settlement response steps 638 and 639.

As briefly described above, the present invention provides a mechanism for 2 utilizing existing account processing infrastructure such as existing point of sale terminals which are generally incapable of inputting additional information such 4 as a transaction identifier into a transaction. In the present embodiment, s associating a transaction identifier to a specific transaction is transparent to an 6 account user, merchant, acquiring bank and bank card association.
Furthermore, because of the services provided by the card issuer to the account manager, the s account manager may establish, edit and delete pre-authorizations at will without exhaustive and expensive account-modifying parameters as historically required.
~o Figure 7 is a simplified transaction diagram for use in wide-area networking environment in accordance with a preferred network embodiment of the present a invention. The present embodiment finds application for use in an environment i3 wherein an account user must divulge an account number in order to make a purchase usingwa transaction device such as a credit card~or other similar device.
is In environments where the physical or personal presentment of such a transaction ib card or device is impracticable such as in a telephonic transaction or in a preferred t7 embodiment such as in the use of a computer network such as the Internet network.
~s Uscrs or consumers have heretofore been reluctant to divulge their account number t9 into an amorphous and unknown domain for fear of an unscrupulous merchant Zo acquiring their account number and utilizing the account number for unauthorized 2t transactions. An account user or consumer has heretofore been required to rely 22 upon the integrity of a remote merchant in order to safeguard against such abuses.
z3 In the present embodiment, however, a user/consumer is issued an account number 24 that when used will be denied unless a specific transaction has been individually 2s pre-authorized by the user/consumer. Such a process is detailed in Figures 7 and 26 8. In Figure 7, in a step 704 a consumer discovers through whatever process the i consumer chooses, a particular product of interest. The consumer may discover 2 such a product either by shopping on the Internet or through other forms of 3 shopping which include other forms of remote shopping such as catalog perusal as 4 well as other imaginable forms of shopping. In prior remote shopping environment s applications, a user would immediately thereupon divulge their account number.
In the present network embodiment, the consumer in a step 702 transitions to a pre-? authorization environment such as a pre-authorization web page on the Internet.
s In the network embodiment of the present invention, the user performs a login 9 procedure or other security procedure for authenticating or otherwise identifying to the accessing user/consumer as being a bona fide user/consumcr. Such an t t authentication process may take the form of a login and password or PIN or other t2 verification or authentication processes known by those .of skill in the art. The is user/consutxter ~ :may alternatively present the account number to such an t4 authorization page, or the authorization page may match the user/consumer's login is and password data with a stored account number. During such a pre-authorization t6 process, the pre-authorization values entered by the user/consumer are stored in a t7 database 704 and may be comprised of an account number, a transaction valid t8 duration (good through) date, a quote or value amount, a variance, and any other t9 miscellaneous identification fields. Upon the termination of the pre-authorization 2o step 702 and the storage in database 704, the pre-authorization information is 2t forwarded to a database that is accessible by the transaction authorizing agent. It 22 should be appreciated that the transaction authorizing agent may be one and the 23 same as the authorization web page provider or any of the other transactional 24 entities including the bank card association or card issuer.
2s Following the pre-authorization process described above, the consumer 26 returns in a step 706 to the web merchant's web page, in the instance of an Internet environment, to proceed with the purchasing transaction. In the' seep 706, the 2 user/consumer offers to the web merchant an account number. In the present embodiment, the user/consumer operating with an account number that specifically 4 requires the pre-authorization process performed immediately above derives a s sense of security knowing that the act of divulging the account number to a merchant would only enable that specific merchant to successfully utilize the divulged account number in at most a single transaction and for a specific amount.
s Therefore, the consumer is protected from unscrupulous merchants that would heretofore misuse a divulged account number.
to Such a pre-authorization embodiment as described herein appears t t transparent to all merchants. Following the account number divulging act by the t2 consumer to the 'merchant, the web merchant in a step 708.performs a traditional i3 authorization request which in a step 710 passes through an acquiring bank, a bank card associationto an authorizing agent. The authorizing agent thereupon performs is an authorization with the account number and any other associated information is passed on from the merchant such as the transaction amount. As part of the authorizing act, in a step 712 the account number with its accompanying tg transaction amount is compared against the previously pre-authorized information which was in the preferred embodiment sent to the authorizing agent for storage as 2o received at the authorization web page. Once a comparison has been made of the Zt pre-authorized "amount" and the transaction amount as received in the a authorization process from the merchant, the authorizing agent will thereafter 23 either approve or deny the transaction according to the pre-authorization 24 parameters. The authorizing agent in a step 714 also subjects the transaction to the 2s traditional standard authorization checks such as credit limits and any variations 26 including an account in good standing. Following the pre-authorization checks in i step 712 and the standard authorization checks in step 714, the authorizing agent Z may thereupon either decline the transaction in a step 716 or approve the 3 transaction in a step 71$.
If a transaction is approved, the pre-authorization process previously s performed is either deleted from the system or deactivated, thereby preventing any 6 unscrupulous suhsequent attempts to utilize the divulged account number. Any additional transactions desired to be performed by the user/consumer require the user/consumer to undergo the pre-authorization process described above in steps 702 and 704. Since each of the pre-authorization requests is valid for only a single to transaction, a particular user/consumer derives additional peace of mind in employing an otherwise vulnerable account number in performing remote t2 ~ commerce such as electronic commerce. .:
~3 Those skilled in the art appreciate that other applications of the above-described technology may also be employed in applications such as transactions ~s engaged in by a user/consumer to other remote entities such as catalog merchants by using a computer interface pre-authorization approach or alternatively through m a telephonic interface which enables a user to specify an account number and a ~8 ~ quotation or potential transaction amount.
Figure 8 is a flow diagram of the immediately above described pre-2o authorization process for use in a wide-area networking environment.
It is appreciated that a potential user of the system would need to establish a an account. In a step 816 a web account user or a consumer 804 interacts with a 23 card issuer 814 to obtain an account number and other various limits such as 2< transaction limits and even specific transaction type limits. Following the 2s establishment of an account step 81b between a potential web account user and a card issuer, a step 818 establishes the authorization restrictions with the authorizing agent 812. While not explicitly shown; the authorizing agent must also 2 be aware of the corresponding account number as welt as the transactional limits 3 and other various limits placed upon a user's account transactions. In one 4 implementation of the present embodiment, card issuer 814 may issue a unique s series of account numbers which uniquely identify to authorizing agent 812 that 6 particular transaction employing such a unique account number require the pre-authorization process before any transactions may be approved.
s Following the establishment of account stage, a user engages in traditional shopping or browsing of the preferred environment, one of which may take the to form of electronic shopping on the Internet. In a step 820,'the web account user t t 804 discovers a web merchant page 806 bearing a preferred good or service to be t2 acquired by web account user 804. In a step 822, web merchant page 806 discloses t3 a price quotation or a quotation amount which may in its simplest form be a textual to listing on the web merchant page of a sale amount. Once a web account user is determines the desirability of a web merchant's good or seivice, the web account t6 user 804 engages in a pre-authorization process with an authorization web page 815 t~ which is affiliated in some manner with a card issuer or other service provider is which presents a front-end interactive environment to the web account user 804.
t9 As alluded to above, an alternate embodiment may employ a telephonic or other 2o interactive front-end enabling a web account user the ability to pre-authorize a 2t forthcoming transaction.
22 In the login step 823, the user may interface with the authorization web 23 page 815 in any of several traditional login procedures such as the offering of a 24 login alpha numeric string followed by the input of a password and may 2s alternatively require the user to enter an account number. In a step 824 the web 26 account user 804 includes the specific parameters within which a forthcoming i transaction must comply. Such parameters may include the divulging of an account 2 number, a transaction amount or quotation amount including a variance which may 3 allow a user to approximate a percentile taxation rate. Alternative parametric information may also include a duration in which a transaction must be performed s else the pre-authorization becomes stale and therefore invalid. The use of a 6 transaction valid duration date also known as a "good through" date enables a user that anticipates an imminent transaction to specify a duration date or time which minimizes the exposure to any account number misuse. In a step 826 the pre 9 authorization request is forwarded from the authorization web page 815 to the authorizing agent 812 that will subsequently perform any authorization requests > > received from a merchant.
~2 Following the pre-authorization phase, the wcb account user 804 returns to t3 the web merchant. page 806 in a step 828 to consummate the transaction by to presenting the web account user's account number. Therea~ftt:r the web merchant is performs an authorization request 830 with authorizing agent 812 in a traditional i6 transaction fashion by submitting an account number and a transaction amount along with any other miscellaneous identifying parameters. Authorizing agent thereafter performs the authorization process described above in Figure 7 and t9 returns in a step 832 an authorization response in the form of an acceptance or a 2o denial of the account number for use in payment for the requested transaction.
Account settlement and account reporting take a similar form as to the other 22 embodiments described in previous figures in that in a step 834 the web merchant 23 requests a settlement with the authorizing agent which thereafter transfers a 24 settlement request in a step 836 to the card issuer which sends payment in steps 838 2s and 839 to the web merchant's acquiring bank. The report accounting stage also t forwards in a step 840 a billing account from the card issuer to the web account 2 user which contains traditional account statement information described above.
Figure 9 depicts a block diagram of an authorization table including both standard and pre-authorization table as stored within an authorizing agent in s accordance with a preferred network embodiment described herein. The 6 authorizing agent described herein in the network embodiment stores an authorization table 900 containing a list of accounts which require pre y authorization as established during an account establishment stage. The authorizing agent upon receiving the established account authorization for a io particular account number populates a corresponding standard authorization table t t 910 with traditional information such as account limits 912, transaction limit 914, t2 and a. balance limit 91G. A particular account such as account number 904 requiring pre-authorization prior to authorizing a transaction also has associated t4 therewith a pre-authorization table 918 which has the corresponding account is number 920 and other pre-authorization fields described herein above. One such tb field is a quotation amount 922 which is the pre-authorized amount that a user/consumer input during the pre-authorization stage. Other values input by the is user/consumer during the pre-authorization phase may include a variance amount t9 and a transaction valid duration or "good through" date as well as any other Zo miscellaneous LD. information. Such information is thereafter referenced by the Zt authorizing agent during an authorization transaction stage.
2Z A particular network embodiment has been described herein having 23 applications to a consumer to business transaction. In such an environment, a user 24 specifically pre-authorizes a forthcoming transaction thereby providing a narrow 2s window in which a transaction must be consummated. By enabling a user to 26 specifically pre-authorize a forthcoming transaction with the inclusion of specific transaction parameters, provides an additional control against misuse of account z numbers which must be divulged to engage in remote commerce where physical presentment of a physical instrument such as a credit or debit card is infeasible.
4 It is contemplated that other remote environments may employ the process as s described herein without departing from the spirit of the invention. Such additional environments and embodiments are contemplated within the scope.
7 The present invention may be embodied in other specific forms without s departing from its spirit or essential characteristics. The described embodiments 9 are to be considered in all respects only as illustrative and not restrictive. The to scope of the invention is, therefore, indicated by the appended claims rather than 11 by the foregoing description. All changes which come within the meaning and t2 range of equivalency of the claims are to be embraced withiwtheir scope.
