RFID system, reader-writer, and RFID tag
Abstract:
A radio frequency identification (RFID) system includes a plurality of RFID tags and a reader-writer. Each of the plurality of RFID tags has a tag antenna and a tag circuit that stores identification information. The reader-writer includes a first transceiver that reads the identification information of the plurality of RFID tags using an antenna. In this regard, the first transceiver transmits a reading command via the antenna for reading the identification information of the plurality of RFID tags. When the first transceiver does not read the identification information from one of the plurality of RFID tags due to an occurrence of a reading error in the first transceiver, the reader-writer adds reading error information, which indicates the occurrence of the reading error, to the next reading command to be transmitted from the first transceiver via the antenna.
