移动支付读卡器的硬件设计

摘要

With the large-scale application, mobile payment has become a hot topic. According to the mobile payment, we will design a card reader. The software uses double micro control unit, and the main micro control can complete serial communication for POS upper monitor. The software also can send command to control the low frequency modules.The software program of slave micro control unit mainly receive and process the command from main micro control unit and call on the underlying program to realize data's manchester encoding to control the distance for swing card. The distance control can't receive low frequency data, and this design solves the problem.%随着移动通信的大规模推广,移动支付已经成为各方聚焦的热点议. 本文针对移动支付系统设计了一款双控制器的读卡器,主控制器主要进行串行通信,从控制器主要接受主控制器命令,根据发送的曼切斯特编码流实现刷卡距离的控制. 这个设计从一定程度上解决了读卡器不能接收低频数据的问题.
