通过FPGA实现的IC卡双卡读写系统

Implementation of Bi-IC Cards Read/Write System Based on FPGA

介绍了一种采用FPGA实现的IC卡双卡读写系统,拓宽了SEP3203微处理器应用范围,并给出了FPGA的具体实现方法和软件设计。该系统通过采用改变片选而不对卡掉电的方法,实现双卡之间的报文鉴别代码验证,用于双卡数据通讯、身份验证、数据存储,并已实际应用于金融收款嵌入式设备中。

A novel bi-IC cards read/write system based on FPGA is introduced, which also widens the area of using microprocessor. Additionally, the implementation and software design are described. The system achieves the verification of message authentication code between bi-IC cards by changing chip select without powering off IC card, which contributes to data communication, identity verification and data storage. And,the system is already employed in the embedded system of financial transaction.
