3、T With the rapid development of electronic information technology, smart cards are now very poplar in our life. Radio Frequency Identification (RFID) card is becoming a new fashion in the application field of smart card, replacing the traditional contacting IC card. So it is of great practical signi

4、ficance to study the technology of RFID Card and develop the read and write device of RFID card for its generalization. In the last few years, non-contact radio frequency cards high security secrecy and use simple and so on characteristics, causes it to be sudden appearance in various domains applic

5、ation, the application prospect is very broad. With the traditional contact card compared, using radio frequency recognition technique development non-contact recognizer, regardless in performance and so on system life, against monitor, against decipher has the very big superiority. Therefore, this

6、article gave using ATMEGA16, MF-RC500, the Mifare card has constructed the non-contact reader-writer. First, this article describes the history,the course, the using in the every walk of life and the future of radio frequency identification technology detailedly.And introducing the merit of the radi

7、o frequency identification technology relative to the traditional technology,and then bring forward the content and the structure of the graduation project. Second, this article includes the operational principle of the radio frequency identification technology system ,and includes the radio frequen

8、cy chip and the inner structure of radio card which are used in the radio frequency identification technology system. Afterward, we discuss and analyse the radio frequency identification technology in various bands of the application and contrast. Third, it gives a practical design, as well as ideas on the design process of the software and the hardware. Finally, it shows the conclusion according to the physical production and the final test results and advances some problems which need us to resolve. Key words: RFID， Mifare card， PICC， RC500
