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. Whereafter, 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 frequence 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 kemel ponents of a Type A IC cards reader, the RF module, what is pletely made by doityourself. In the end, the paper introduces the software of the system, and the main property and basic intruction set of a contactless IC card reader RC500 based on Philips’MIFARE1 are introduced. And some ideals and methods of programme about the basilic module with data munication between the cards and RC500 are presented. Finally, introduced the system design part of the software and the PCB circuit diagram, and the actual test results show that the reader to plete the basic functions, stable operation .The ReadWrite Device is stabilized through test.
