PURPOSE:To secure the identification of an individual and to prevent an IC card from being used by a third person by storing physical characteristics such as a fingerprint, a voiceprint and features which a user has in the IC card, and collating the physical characteristic of the user at the time of transaction. CONSTITUTION:The user of the IC cad previously stores the physical characteristic such as the fingerprint, the voiceprint and features which the user has in the memory of the IC card 1 as image data. At the time of transaction, image data stored in the IC card 1 is read, and the physical characteristic is obtained from the image data, whereby the physical characteristic and that of the user at the time of transaction are collated. If the coincidence of the physical characteristics is recognized by the collation, transaction is executed, and in case of discrepancy, it is not executed. Thus, the IC card is prevented from unauthorized use by the third person. |
