IC TAG WITH DAMAGE DETECTION FUNCTION

摘要

PROBLEM TO BE SOLVED: To prevent unauthorized action such as falsification and fabrication of recorded contents by complicating removal of a tag adhered to an article or inside a vehicle/housing.

SOLUTION: An inlet 5 is formed by joining an antenna coil 2 and a fracture switch 3 to an IC chip 1 on a substrate 4 such as a PET film. The fracture switch 3 breaks and disconnects a circuit when a tension stronger than specified one is applied. The inlet 5 applies an adhesive agent (a) to the outer periphery of the upper surface of the substrate 4 and to the top surface of the fracture switch 3 to cover an upper surface with a surface seal 6 and applies the adhesive agent (a) to the entire lower surface of the substrate, and the lower surface is supported by release paper 7 to which release processing of silicone is applied. The inlet 5 is adhered to the articles or places by peeling off the release paper 7.
