摘　　要：针对射频识别技术电子支付系统普遍存在的读卡缓慢、效率低和稳定性差等问题,本文设计了基于STM32微控制器和射频识别技术读卡器的电子支付系统。系统选用STM32F407ZET6作为主要控制处理器芯片,读卡器选用广州思腾公司的ST_RF04,卡片选用飞利浦公司生产的M1(mifare one)S50卡,并通过RS_485实现实时通讯;同时,在KEIL-MDK的软件开发平台上,开发支付系统的软件程序,实现读卡、写卡、充值、扣款等功能。测试结果表明,该系统实现了对M1卡的高速读写等功能,具有稳定、快捷和高效的特点,满足人们对电子支付系统高效安全的要求。因此,该研究在电子支付方面具有广阔的应用前景。Aiming at RFID electronic payment system's problem in slow reading speed low efficiency and poor stability,this article designs an electronic payment system based on STM32 micro controllers and RFID card readers.This system uses STM32F407ZET6 as main microprocessor,ST_04produced by Guangzhou Siteng company as card reader,M1(mifare one)S50produced by PHILIPS as card,and it realizes the instant communication by RS_485protocol.On the IDE of KEIL-MDK platform,we design electronic payment software program including the function of read-card write-card recharge and reduction.Test result shows that this system can read and write M1 card at high frequency and high efficiency,which meets people's safe efficient need to electronic payment system.So this study possesses prosperous practical prospect in electronic payment aspect.
