As the ubiquitous information society is truly being realized, the need to identify individuals is increasing in municipal, traffic, financial and administrative services, medical treatment and welfare, education, and other such fields. In conventional authorization by means of credit cards, etc. (confirmation of validity by expiration date, detection of misuse, etc.) and authentication on the Internet (confirming legitimacy over a network by means of entry of a user ID (identification) and password, etc.), confirmation of the identity of the user is indirect. Hitachi, Ltd. has developed a solution based on traceability that is achieved with ultra-compact, non-contact technology and IC (integrated circuit) chips and a new card standard that combines IC cards and memory.
