摘要

The contactless IC card becomes the potential biggest new armed forces to be subject to the domestic and foreign fields the attention in the IC card by its non-machinery to maintain, wears easily, convenience used and so on merits. The microcontroller unit STC89C52 is used, one kind of reader is designed, it including two parts:the hardware and the software. The hardware including the microcontroller unit, the radio frequency cards reader module, the antenna, the radio frequency card, the serial communication connection, the keyboard, LCD, serial EEPROM and so on. The software including the master program, reader subroutine, display subroutine and so on. The source program is writed with C or the assembly language, it is compiled on the Keil uvision3 platform, after throughing and it is downloads to the microcontroller unit STC89C52, this microcontroller unit and other primary device is welding on the PCB board, and the Mifare card is laid aside in the antenna area coverage, the serial port is connects better, puts through the power source, may carry on “the data reader” and so on operations, It indicated that has achieved the design requirements.
