PROBLEM TO BE SOLVED: To provide a non-contact IC card which can easily switch the non- contact IC card to a use impossible state from a use possible state and again to the use possible state and which can securely discriminate that the card is already used. SOLUTION: In the non-contact IC card 10, a simple shorting circuit by an anisotropic conductive material is formed between terminals where both terminals of an antenna coil are connected to an IC chip. When the circuit is shorted, the non-contact IC card is not functioned and the function of the non-contact IC card 10 is restored when the shorted circuit is cut. Thus, a use possible state can easily be switched to a use impossible state and further to the use possible state. An anisotropic conductive film and adhesive can be used for the anisotropic conductive material. The simple shorting circuit is formed by making it pass through a cut piece provided by extending it to a card base main body part. Consequently, the card can securely be discriminated to be already used or not used by the presence or absence of the cut piece. |
