Internal) Exchange data. This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID. It was originally promoted by Philips, Nokia and Sony, and is mainly used in handheld devices such as mobile phones. FC combines contactless readers, contactless cards and Peer-to-Peer functionality into a single chip, creating countless new opportunities for consumers' lifestyles. This is an open interface platform that enables fast, proactive setup of wireless networks and is a virtual connector that serves existing cellular networks, Bluetooth and wireless 802.11 devices.

The implementation process of the embodiment of the present invention will be described in detail below in conjunction with the preferred embodiments. First of all, it should be noted that, considering that the FC terminal communication application is too broad, the present invention only uses the FC mobile phone Bluetooth payment as an entry point of the preferred embodiment, and is described in detail. At the same time, in addition to the payment function, other applications that use the Bluetooth/WIFI technology to extend the NFC communication distance and communicate, other terminals (such as PSP, PDA, etc.) using the present technology to extend the FC communication distance should also be included in the scope of protection of the present invention. Secondly, it should be noted that the following preferred embodiment has assumed that the mobile phone user already knows that the Bluetooth device name XD001 and the pairing code of the card swiping machine are 123456. Preferred Embodiment 1 FIG. 7 is an interaction flowchart of a near field communication method according to a preferred embodiment of the present invention. As shown in FIG. 7, the following steps S702 to S742 are included. Step S702, first, when the mobile phone user determines that the payment distance is insufficient, the mobile phone Bluetooth device is started to search for the credit card machine. Step S704, the mobile phone side sends a broadcast command through Bluetooth to search for the Bluetooth device. 8 is a schematic diagram of a Bluetooth mobile device search card reader according to a preferred embodiment of the present invention. As shown in FIG. 8, there is an obstacle between the FC terminal and the plurality of card readers, and the FC terminal sends a broadcast command through Bluetooth to search for the Bluetooth device. . Step S706, the card swiping machine returns its own Bluetooth device name XD001 after receiving the broadcast message (generally, since the card swiping machine is generally unlikely to do too much operation, the Bluetooth card is turned on by default, and the credit card machine name and pairing code are enabled. Both should be marked in a prominent position for the user to read.). Step S708, the card reader sends its own device name to the mobile phone via Bluetooth. Step S710, after the mobile phone search ends, it is determined whether the credit card machine XD001 needs to be paid, is to the step

S712, No, search again. Step S712, since there may be multiple Bluetooth devices, the mobile phone user needs to select the card reader XD001 and input the pairing code. Step S714, the mobile phone sends the pairing code 123456 via Bluetooth. Step S716, the card reader determines whether the pairing code matches, and returns the pairing result. Step S718, the card swipe machine sends the pairing result to the mobile phone Bluetooth device via Bluetooth. Step S720, the mobile phone receives the pairing result, and determines whether the pairing is successful. If the pairing succeeds to step S722, the pairing fails to display the pairing failure, and the process goes to step S712. Step S722, the mobile phone sends a payment instruction through Bluetooth. Step S724, the card reader displays that the NFC mobile phone is in the payment state, and proceeds to step S726. Step S726, the cashier selects the mobile phone, inputs the payment amount, and starts the payment process. Step S728, the card reader packs the payment data and sends it through Bluetooth. Step S730, the mobile phone waits for the Bluetooth data of the credit card machine, and parses and sends the data to the SE module. In step S732, the mobile phone reads the data of the SE, and proceeds to step S734. Step S734, the data read by the mobile terminal group packet SE module is sent through Bluetooth. Step S736, the card reader receives the Bluetooth data on the mobile phone side and parses it, and sends it to its own SE module. Step S738, the card reader reads the SE module data to determine whether the payment is over, to step S740, and to step S728. Step S740, the card reader sends the payment result through Bluetooth. In step S742, the mobile phone side displays the payment result, and the entire payment ends. The present invention also provides an example for describing the above-mentioned FC mobile phone Bluetooth payment, which will be described in detail below. When a user needs to pay 100 yuan across an obstacle, the name of the machine is LM01 and the Bluetooth pairing code is 123456. The user finds that the current distance does not meet the FC card swipe distance. At this point, the Bluetooth device search card reader LM01 is turned on, and the machine that needs payment is found. Select this card reader and enter the pairing number 123456. If the input is correct, the pairing should be displayed successfully. At this time, the card reader interface will have a mobile phone that needs to be paid. The cashier simply clicks on the mobile phone and enters the amount of 100 yuan. At this time, the user's mobile phone side will pop up the deduction button: "LM01 POS machine applies for deduction of 100 yuan, please confirm." As soon as the user clicks OK, the payment process begins. After the payment machine confirms the payment is successful, a payment end command will be sent through Bluetooth to notify the mobile phone user that the payment is over. Such an application to extend the payment distance of the FC mobile phone via Bluetooth is realized.
