The Design of Passive RFID Reader System Based on MF RC500

摘要

RFID is a technology that uses radio frequency signals coupled to the space (alternating magnetic or electromagnetic), to achieve the purpose of non-contact transfer of information and automatic identification. In this paper, RFID reader system is designed based on the MF RC500. Compared with the automatic identification technology such as the barcodes, magnetic cards and IC cards, The RFID reader has many outstanding advantages: firstly, it is safe and suitable for high security terminal. The second, a plurality of electronic tags can be recognized simultaneously. The third, there is no mechanical wear. The fourth, it is convenient to use with non-contact operation and without human intervention when identifying.
