射频卡读写器，超过PHILIPS的射频基站，可读写14443，13956等协议的卡。加密强度目前可能是最高的。价格便宜。-RF card reader, more than PHILIPS radio base stations, read-write the agreement, such as the 14443,13956 card. The current strength of encryption is the highest. The price was cheap.

这个是STM32 MODBUS程序 经过测试可以用，串口加定时器中断实现数据传输。3.5个字符时间收不到数据即认为是一帧数据发送结束。

应用背景我本科电子工程师做工程近日从巴基斯坦u.e.t塔克西拉。关键技术我已经做了这个代码最近我的类项目的帮助下，我的类研究员。
