<p><P>PROBLEM TO BE SOLVED: To enable rapid and proper communication with a number of RFID tag devices. <P>SOLUTION: The RFID sensor system comprises first and second conduction paths 2 and 3 for transmitting signal from an RFID detection driver 1, a controller 4 connected to the first and second conduction paths 2 and 3, and a reader 5 connected to the controller 4. Since the RFID detection driver 1 is connected capacitively or directly to the first and second conduction paths 2 and 3, supply of power to the RFID detection driver 1 and receipt of detection signal from the RFID detection driver can be performed without providing a plurality of antennas on the RFID detection driver 1, and the structure on the reader 5 side can be significantly simplified. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
