<p><P>PROBLEM TO BE SOLVED: To provide an RFID tag preventing an illegal use. <P>SOLUTION: The RFID tag includes an antenna for transmission and reception; a detector formed in the periphery of the antenna; and an electronic component, connected to the antenna and the detector, for detecting a break of the detector. With the above structure, illegal use can be prevented, and while including the detection means, matching of the tag antenna and the IC chip is obtained, so that a high antenna radiation/reception characteristic can be obtained without losing an antenna gain. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
