<p><P>PROBLEM TO BE SOLVED: To provide a technology for reducing interference waves occurring between a plurality of reader/writers in the environment in which a plurality of RFID systems operate. <P>SOLUTION: The system comprises a plurality of reader/writers and a control device 1100 for controlling them. Each reader/writer comprises a main body 500 (1000), antennas 200-202 (700-702), and a distributer 400 (900) for selecting one antenna from among the antennas 200-202 (700-702). The control device 1100 selects an antenna which is situated for least interference waves from among the antennas 200-202 (700-702) posessed by the reader/writers, and commands the main body 500 (1000) of the reader/writers. Each reader/writer selects one antenna from the antennas 200-202 (700-702) based on the command from the control device 1100, and transmits the command to an RFID100 (600). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
