Abstract

PURPOSE:To protect an IC card until just before it use by enabling its unfair use by a third party to be discriminated and preventing an internal data from being electrostatically destructed by a method wherein a false adhesive layer is stuck to an external contact terminal in the IC card having the external contact terminal. CONSTITUTION:An IC card has a semiconductor integrated circuit built-in, and is equipped with an external contact terminal 2 for giving and receiving data with a reader-writer at least on a part of a surface. In that case, a false adhesive layer 3 is stuck to at least a part of the external contact terminal 2. Then, the false adhesive layer 3 is tuck by adhesive force to the extent wherein, for example, when once peeled off, it can not be stuck again, and prevents destruction or the like of the data owing to static electricity from outside by using a seal having an insulating property. Further, a hologram seal which is high in a forgery preventive effect, a notched seal wherein when once peeled off, it can not return to an original state, etc., may be used. Furthermore, the false adhesive layer 3 is stuck in manufacture and in issuing.

別判断することは出来なかった。However, such an IC card has an external contact terminal for connection for electrically and mechanically connecting the IC circuit and an external data processing device for information exchange. Since it has electrodes, there are problems such as data destruction due to static electricity from the outside of the IC circuit and unauthorized use such as data rewriting by a third party. Also, IC
