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.

Data processing method based on NFC label, system and server thereof

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. The signal enhancer and chip, as the trunk device between the dual interface SIM card and the reader, can enhance the acknowledge signal of the dual interface SIM card and ensure the normal communication between the dual interface SIM card and the reader.
