<p><P>PROBLEM TO BE SOLVED: To solve problems that a counterfeit prevention label and a tag for counterfeit preventions themselves can be forged and that identification is not easy and usability is not good by measures which need a complicated procedure, even if the measures for preventing the counterfeit is taken against an expensive article. <P>SOLUTION: The reliability for identification is increased and an appraisal of a genuine article and counterfeit is surely carried out by performing identification using a radio communications system by a counterfeit prevention system made up by combining an IC tag 1 for counterfeit prevention with an identification device 2 for counterfeit prevention. The IC tag 1 is provided with; an antenna 15 for receiving a radio wave;a power generation circuit 16 which carries out self-excitation power generation by rectifying received radio wave; an EEPROM 13 which is a storage; an RF driver 11; and RF receiving circuit 12. The identification device 2 is provided with; an RF driver 25 for supplying the radio wave; an RF receiving circuit 26 which receives radio output; an EEPROM 24 which stores data; a CPU 20 which compares the data stored in the EEPROM 24 and received information received in the RF receiving circuit 26; and a liquid crystal display part 22 which displays a comparison result from the CPU 20. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
