摘　　要：为了加速校园信息化建设,实现校园一卡通系统,设计了RFID读写器。首先概述了RFID读写器的基本原理及结构框架,并对MFRC522芯片做了简单的介绍和说明,然后给出了实际的电路原理图及天线计算方法,并根据关键寄存器的设置给出了对Mifare卡完成读写基本功能的流程图,完成了基本的身份识别和电子钱包等应用。结果表明,读写器读写数据准确,易于扩展,有一定的发展空间。To speed up the campus information construction,and realize the campus card system, the RFID reader is designed. Firstly; it is summarized which includes the basic principle and the structure of RFID reader. The MFRC522 chip is introduced in the paper, and also the circuit diagram and the calculation method of antenna. The flow chart is introduced for reading and writing Mifare card according to setting the key registers. The application of basic personal identification and electronic wallet are completed. The results show that data transmission is exact, and it is easy to expand with a further development potential
