Passive RFID Attendance System Based on MSP430
基于MSP430的无源RFID考勤系统

With the developing of information technology, smart attendance system has been an essential facility for modem enterprise. In this paper, a low-power RFID system based on MSP430 and TRF7960 is designed. The reader can inquire passive tags which support ISO14443A protocol and has been planted with anti-collision algorithm. It has a read range of 8cm and can read 2 tags at the same time. Experimental results verify that the RFID reader is stable and reliable. Combined with the development of middle-ware and Web service application at the server, a complete solution of attendance system is achieved.
