Research and Design of UHF RFID reader

The system of UHF RFID has the advantages such as storage capacity, read and write speed, recognition distance, and can read or write multiple RFID tags simultaneously, which has been applied widely in many fields. In order to meet market requirements, this paper proposes a design project of a UHF RFID system interrogator based on ARM. In this paper, two aspects of hardware and software design of the interrogator are described, the design gives the structure of interrogator, work processes and the related flow chart of software. The practical results show that the interrogator has the advantages of read and write speed, efficient read-write, recognition distance and so on, which can meet market requirements.
