<p>PROBLEM TO BE SOLVED: To provide a tag IC with which information included in the tag IC can be read even though a reader is far away from the tag IC by intensifying a radio wave emitted from the tag IC. SOLUTION: This tag IC is provided with an antenna 2 transmitting and receiving a signal to/from a reader by AC electromagnetic energy, an IC chip 1 decoding received data from the reader and operating and transmitting transmission data on the basis of included data, and a solar battery 3 directly converting light energy into electric energy and feeding power supply to the IC chip.</p> |
