Abstract:With micro-computer STC89C52 as controller, the radio frequency technology as core, this paper describes the system’s composition、work principle and design of hardware and software of contactless IC card read-write device base on MF-RC500 of PHILIPS Company .

  This paper introduces the basic principle of the contactless IC card technology and the application of IC card reader. First the paper describes the development and the status quo of the IC cards system. Then the work principle of the radio frequency IC card system is discovered through studying the principium of the radio frequency technology. Where, the paper introduces the card MF1 IC S50 what is usually used in the cards of Type A, the design method and the circuit of the card reader device (the device use the radio frequency chip reader module RC500), and in detail analyzes the principle of every module, simply Points to the design rules of the antenna circuit. Then, the paper in detail introduces the implement project about circuit and program of the  components of a Type A IC cards reader, the RF module, what is completely made by do-it-yourself. In the end, the paper introduces the software of the system, and the main property and basic instruction set of a contactless IC card reader RC500 based on Philips’MIFARE1 are introduced. And some ideals and methods of program about the basic module with data communication between the cards and RC500 are presented. Finally the two examples of program are given. The Read-Write Device is stabilized through test.
