<P>PROBLEM TO BE SOLVED: To provide an IC tag unit that ensures high security even while maintaining convenience, and a management system employing the IC tag unit. <P>SOLUTION: The IC tag unit 10 includes an IC tag 20 and a state detection sensor 12 for detecting that a specific operation is applied to an operation unit 14. The state detection sensor 12 is made conductive by connecting terminals 12A, 12B with an interconnect line 12C before the specific operation is applied, and is made non-conductive by disconnecting the interconnect line 12C from the terminals 12A, 12B after receiving the specific operation. Moreover, the non-conductive state is irreversible to the conductive state. The IC tag 20 stores specified article information in a memory unit, if a write instruction is issued from a reader/writer device. However, even if the write instruction is issued, the specified article information is discarded when the state detection sensor 12 is in the non-conductive state, the operation of a processing unit is terminated without storing the specified article information in the memory unit. <P>COPYRIGHT: (C)2011,JPO&INPIT |
