Abstract: The invention relates to a data processing method based on NFC tag. The method comprises: reading the NFC tag, the NFC tag comprising tag content and tag ID; generating an NFC tag payment request based on the tag content and tag ID; parsing the NFC tag payment request and obtaining an parsing reply to the NFC tag payment request; generating an order generation request based on the parsing reply, wherein the order generation request is for causing an order to be generated based on first account information, current transaction information and second account information; generating the order based on the order generation request; and payment step for performing payment based on the order. According to embodiments of the invention, the payment process can be simplified, also, there is no need to set the NFC-specific reading device in the embodiments of the invention, and the cost of merchants can be reduced.

Abstract: The invention relates to a data processing method and a system based on NFC tag. The method comprises: acquiring amount data; generating custom order number for identifying a transaction; issuing tag data application request based on original NFC tag data, acquired amount data and custom order number; generating updated NFC tag data based on tag data application request and saving custom order number, and setting payment state for custom order number to be the unpaid state; updating the NFC tag based on the updated NFC tag data to obtain an updated NFC tag, wherein the updated NFC tag includes amount data; and reading the updated NFC tag and completing payment processing based on updated NFC tag. According to embodiments of the invention, it does not require transaction amount to be input by the user's mobile phone terminal, but instead, transaction amount is obtained by tag receiving terminal through input device.

Abstract: A signal enhancer chip for a radio frequency identification system and a signal enhancer are disclosed. The signal enhancer chip includes: a receiving circuit, a sending circuit and a power supply module. The receiving circuit comprises a demodulation amplification module and a digital quantizing module. The sending circuit comprises a logic control module and a modulation module. The demodulation amplification module is for amplifying and demodulating the received communication signal sent by a dual interface SIM card. The digital quantizing module converts an analog communication signal output from the demodulation amplification module to the digital communication signal. The logic control module processes the digital communication signal output from the digital quantizing module and generates a subsidiary carrier wave signal necessary for returning to a reader. The modulation module generates a communication signal to be sent according to the subsidiary carrier wave signal.
