摘　　要：介绍非接触式IC卡的特点,讨论基于便携式应用的非接触式IC卡读写器的实现方法。该读写器采用USB接口取代原来常见的RS 232接口,采用AT89S52作为MCU,采用Philips公司的兼容ISO14443A规范的读卡器专用集成电路RC500,带有充电电路、锂电池和液晶显示,实现了可脱机使用的便携式非接触式IC卡读写器。实际使用表明,该读卡器性能稳定,功耗低,抗干扰能力强,免接触读写距离可达10 cm。A method which is used to design a portable contactless IC card reader with USB interface is introduced.The reader is based on chip AT89S52 with interface device using FT245BM and with help of ISO14443A compatible reader chip RC500,with Li-ion battery,charger and LCD.A portable contactless IC card reader with USB interface is realized.The practical operation verifies the stability,low-power consumption and strong interference immunity of this Mifare IC card system,and its reading and writing distance can reach to 10 cm.
