摘　　要：非接触式IC卡技术成功地将射频识别技术和IC卡技术结合起来,解决了无源、免接触问题;该非接触式IC卡读卡器是以射频识别技术为基础,以Mifare卡作为读卡器识别对象,采用非接触式IC卡读卡器核心读写模块MFRC500和单片机来设计的;具体阐述了非接触式IC卡读卡器硬件电路和软件开发,给出了硬件原理图并对其作了详细的说明;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10cm。The technology of Mifare IC card, integrates the RFID and IC card successfully, also brings the solution to the problem of powerless and touch free of IC card, The touch free IC card reader based on the RFID technology, with its identification object Mifare card. The core parts of the system is the MCU and reading and writing module of Mifare card MFRC500. This article mainly introduced the design methods of IC card reader, sufficiently described the development of circuit and system software, and presented the hardware schematic in details. 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 10cm.
