Abstract

The embodiment of the present application provides a smart card writing method and device, which solve the problems of low security and poor scalability of the existing smart card writing method. The smart card writing method includes: when the smart card information is read through the card socket interface, the translation of the interface protocol is performed through the first chip, so as to establish a wireless communication connection with the user's mobile terminal through the communication interface module; When the module receives encrypted payment information from the user's mobile terminal, it processes the encrypted payment information through the second chip to complete the card writing process; and encrypts the recharge result generated by the second chip, and passes the communication The interface module returns the encrypted recharge result to the user's mobile terminal.

Description

technical field [0001] The present application relates to the technical field of electronic communication, and in particular to a smart card writing method and device. Background technique [0002] There are 4.39 million smart users of IC cards and CPU cards in Beijing. The existing technology provides some self-service recharge terminals to solve the trouble of smart card meter users going to the bank counter to buy gas. When individuals go to the bank to recharge and purchase gas, firstly, they waste a lot of precious time, secondly, it increases the workload of the bank, and thirdly, because the bank charges commissions, it is also a cost for the intelligent group. On this basis, Smart Group has developed a self-service recharge terminal. However, the self-service recharge terminal is expensive, occupies a large space, and needs an indoor placement place. However, individuals still need to go to a designated limited place to recharge. [0003] The prior art also provide...
