The type of said card comprises M1 card and CPU card; Among the said step b, when this prepaid terminal is chosen card, distinguish the type of choosing card,, then jump to step c if the card of choosing is the M1 card through the inquiry response and the response command that resets.
As one embodiment of the present of invention, M1 card and CPU card and deposit use in the system, the user pays dues and purchases electricity, and business personnel handle neocaine for the user or supplement old card with money through IC-card sale of electricity management software, according to the pay tariff electric weight of purchasing IC-card are supplemented with money.Each uses the user of M1 card can only use fixing card, and use CPU card can be general, and the salesman can suggestion use the CPU card instead when each M1 card user is supplemented with money.The CPU card is only used at new terminal, and the card of newly opening all uses the CPU card.In the system M1 card and CPU card are distinguished use; The M1 card can only be used for corresponding prepaid terminal system corresponding prepaid terminal is issued in UID number of M1 card; And the CPU card does not limit, can be general in prepaid terminal, can support in the future and the interconnecting of other charging system.The use of CPU card is only supported at new terminal, no longer backward compatible M1 card.
Fig. 2 shows the prepaid terminal upgrade method of use M1 card of the present invention.The M1 card is consistent with the CPU card on the hardware of card-reading terminal, on the initial operational order of seeking card, anti-collision, choosing card, also is consistent.After choosing card is accomplished, can distinguish what choose card through the inquiry response and the response command that resets is CPU card or M1 card.What originally use the pre-payment negative control terminal of M1 card to differentiate in choosing card back to choose is M1 card or CPU card, M1 card in this way, and then according to original program circuit, if what choose is the CPU card, then need be according to the operating process of CPU card.Original terminal need be in the program of updating operation CPU card on the software and the Card Type decision behind the increase choosing card.
For the prepaid terminal that uses the M1 card, need on the basis of original operation M1 card, increase the UID checking of M1 card.When the M1 card is sought at the terminal, read the M1 card earlier UID number, and with the UID that reads number with the terminal in store make comparisons for available UID number.Can issue by main website is online for the UID that stores in the terminal number, also can be by staff's manually input voluntarily on the terminal.If the UID of the card of reading number with the terminal on store do not meet for UID number, then the terminal is sent warning information and on display screen, is shown error message, other card that is cracked can not have any impact to the terminal in the system like this.
Fig. 3 shows a kind of prepaid terminal operating process of this method.
At first be the terminal seek card, anti-collision, the operation of choosing card, choose card after, differentiating what choose is CPU card or M1 card.If what choose is the CPU card, then operate according to normal CPU card.If what choose is the M1 card, need read the M1 card UID number, and with the UID that reads number with the terminal in store do this available UID number.
If UID number of the M1 card of reading with the terminal on store be consistent for UID number, the terminal is to sticking into capable cryptographic check.With the password that generates card for UID number of card, accomplish that a card one is close during hair fastener., can directly read the corresponding UID password that is stored on the terminal and come check card during check card at the terminal.If cryptographic check is not passed through, then the terminal is sent warning information and on display screen, is shown error message.
If the terminal is passed through the cryptographic check of card, whether terminal inquiry self is online.The terminal at set intervals can with master station communication, reporting information if do not receive master information for some time, then can be considered not online.If the terminal is online, corresponding UID number the electricity charge value of storing in the electricity charge information in then the terminal will be blocked and the terminal is made comparisons, if meet; Then accomplish bankcard consumption; And card using information reported main website, main website is again with the operation sheet number of times zero clearing of writing down in the terminal, and revises corresponding UID number electricity charge value.If do not meet, then the terminal is sent warning information and on display screen, is shown error message.Main website is handed down to charging information at UID number terminal of corresponding card after the user pays dues and card supplemented with money.The terminal is when user card punching like this, if judge that oneself is online, the electricity charge information that then can come card authentication with the electricity charge information of oneself storing earlier is after completion is swiped the card, again with information reporting.
If the terminal is passed through the cryptographic check of card, and the terminal is found self to be in off-line state.The operation sheet number of times of terminal inquiry self, if greater than the value of setting, then the terminal is sent warning information and on display screen, is shown error message.If the operation sheet number of times is less than the value of setting, then the operation of swiping the card is accomplished at the terminal, and the operation sheet number of times is added 1, then with this information storage of swiping the card in the terminal.When being connected to main website once more, this card using information is reported at the terminal.The user possibly taken place during the terminal off-line paid dues and dash value, and main website can't notify the terminal.So when swipe the card at offline user in the terminal, can not verify the electricity charge information of oneself storage again, and the operation of must completion once swiping the card.If do not adopt the mode of terminal and card UID number pairing, even limited each UID number the number of times of swiping the card, a large amount of different UID number card possibilities of swiping the card of duplicating still possibly appear, cause electricity charge loss.The mode that adopts terminal and card to match; Have only corresponding UID number card can on the terminal, accomplish the operation of swiping the card; If the off-line of the setting number of times that allows to swipe the card is made as 1, so same UID number duplicate card and can only use once, and because UID number unpaired with other terminal; Can not possibly use on the terminal of off-line at other, also can not cause electricity charge loss like this under the off-line state.And the mode of terminal and card pairing can prevent also that user's card from being usurped because of carelessness and duplicate, even block stolen duplicating like this, can not on other terminal, use, and can not cause damage to the user.
The present invention's UID number of locking M1 card in the prepaid terminal that uses the M1 card overcome prepaid terminal and progressively has been upgraded in the process of CPU card system in M1 card system, when two cards and when depositing because the safety issue that the M1 card is cracked system is brought.Simultaneously the M1 card is bundled in the old terminal and uses, and newly-built terminal need not the compatible M1 of use card, can use as pure CPU card system, need not to upgrade once more in the future.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
