Study on the Frame of MIFARE Contact-less IC Card Reader YAN Xiong-wu,LIANG Chu-qiao(School of Information Engineering, Wuhan University of Technology, Wuhan 430070, China)The technology of contact-less IC card is a technology that combines the radio frequency identification with the IC card technology. Contact-less IC card reader is one of the key application of IC card. Based on technology of radio frequency identification and ISO14443 protocol, a method used to design contact-less IC card reader was presented by using the core module of contact-less IC card reader and RISC single chip microprocessor and by taking the MIFARE card as the object of identification. The internal structure of contact-less IC card and its operational principle was introduced briefly. The designs of hardware and software were described in detail. The reader has many good features, such as reliability, low power consumption and high performance of anti-interference. Its operation distance can reach about 100 mm.contact-less IC card; RC500; ISO14443A; reader
