<P>PROBLEM TO BE SOLVED: To provide an electromagnetic induction type sticker that ensures tampering detection from the breakage of printed wiring due to intentional peeling of the seal by slitting a surface film protecting the wiring. <P>SOLUTION: The electromagnetic induction type sticker, which is so designed that a current flowing through a coil 2 of a processing result reading device 1 generates a magnetic field, the magnetic field generates a current through a printed coil antenna 3 by electromagnetic induction, and the current activates an IC chip 4 connected to the antenna 3 to read the input information, has a plurality of perforations 10 across the antenna 3 in an upper surface of the electromagnetic induction type sticker 5, so that the peeling of the electromagnetic induction type sticker 5 from an object breaks the antenna 3. <P>COPYRIGHT: (C)2007,JPO&INPIT |
