摘要: Disclosed herein is a Radio Frequency Identification (RFID) system and method for controlling distance ranges. The RFID system includes a plurality of RFID tags, a plurality of readers, and middleware. The RFID tags receive position coordinates and time data through signals from a satellite and store data. The readers transmit and receive data to and from the RFID tags. The middleware forms a network in conjunction with the readers and controls distance ranges between the RFID tags and the readers.
