METHOD FOR PROCESSING PAYMENT BUSINESS AND TERMINAL

摘要

The present invention provides a terminal, and a method for processing payment business. The terminal comprises a near field communication function module and a processing module. A security unit in the near field communication function module is connected to the processing module; the security unit stores a mobile payment security application which includes user payment information. The mobile payment security application is used, after receiving a payment request, for sending the user payment information to the processing module, and, after receiving a user information ciphertext sent by the processing module, for sending the user information ciphertext. The processing module is used for performing an encryption algorithm according to the user payment information so as to obtain the user information ciphertext, and sending the user information ciphertext to the mobile payment security application. The present invention enables a Near Field Communication (NFC) device to be able to use more complicated and highly functional encryption and decryption algorithms, so that encryption and decryption abilities of the NFC device are enhanced, and security of the NFC device as a means of payment is increased.
