RFID技术的电子市民卡系统设计与实现

以51系列单片机为控制核心,设计了基于MFRC500的射频识别（RFID）电子市民卡系统,可实现身份识别,电子病历,公交、物业等电子支付,电子钱包等功能.射频卡使用符合ISO14443A协议的MIFARE卡,通过环形印刷电路板（PCB）天线与读卡器之间通信实现系统功能.系统通过加密算法对读写器和卡片之间传输的数据进行加密,并在读写器以及上位机上设计更为安全有效的认证方案,使得系统整体安全可靠.

Design and development of an electronic public citizen card based on RFID

A radio frequency card, also known as a non-contact IC card, is an emerging field of technology. A radio frequency identification （RFID） electronic public citizen card was designed based on MFRC500, which adopts 51 series microcontroller unit as the core, can achieve identification, electronic medical records, public transportation, property and other electronic payments, electronic purse functions. The RF card uses the MIFARE card which is in compliance with ISO14443A protocol to realize system function through communication between the card reader and the loop antenna consisted of printed circuit board （PCB）. The system encrypts data transmitted between the card and the card reader. Besides, more effective certification program was designed for the reader and the host computer, making the whole system safe and reliable.
