摘　　要：针对A类接口的读写器不能对B类CPU卡进行读写的问题,介绍一种可以对3V的B类卡片进行读写的5V接触式IC卡读写器,阐述了其硬件电路结构和单片机固件程序,介绍了对其进行操作的简单上位机软件。实验结果表明,该读写器结构简单、性能稳定,对研制可同时操作3V/5V卡片的AB类接口设备有指导意义。For B smart card can not be manipulated by the reader with class A interface, in this paper, a contact reader/ writer of 5 V source for B smart card of 3 V source is introduced. Hardware circuit design and firmware is discussed separately. Finally, the simple application software is introduced. From the running of the system, it shows that the reader/writer has a simple structure and stable performance, providing furtherance for development reader/writer for 3 V/5 V smart card.
