Abstract

In recent years, the technology of RFID developed rapidly, and has been used more and more widely. In this paper, using the Texas Instruments semiconductor chip of TRF7960 and the single-chip microcomputer of PIC16F877, a new design scheme of RFID reader is proposed, which conforms to ISO/IEC 15693 standard. The reader operates in 13.56MHz and can identify the tags in about fifteen centimeters. The hardware design and the software flow are provided in detail. Test results present that the functions of anti-collision and multiple tag identification are supported in this reader, it has high accuracy ratio when reading and writing tag.
