Radio Frequency Identification (RFID) card is being a new fashion in the application field of smart card, replacing the traditional contacting IC card. So it is of great practical significance 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, noncontact radio frequency cards high security secrecy and use simple and so on characteristics, causes it to be sudden appearance in various domains application, the application prospect is very broad. With the traditional contact card pared, using radio frequency recognition technique development noncontact recognizer, regardless in performance and so on system life, against monitor, against decipher has the very big superiority. Therefore, this article gave using ATMEGA16, MFRC500, the Mifare card has constructed the noncontact readerwriter. First, this article describes the history,the course, the using in the every walk of life and the future of radio frequency identification technology introducing the merit of the radio 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 frequency 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.
