AUTHENTICATION SYSTEM

摘要

It is possible to provide a safe and user-friendly authentication system for authenticating an object required in various conditions. The authentication system (900) includes a first authentication information transmission device (901) having first authentication information, a second authentication information transmission unit (904) having second authentication information, and an authentication unit (905) for authenticating a user or user's right. The second authentication information transmission unit (904) transmits second authentication information only while it receives the first authentication information transmitted from the first authentication information transmission device (901). The authentication unit (905) receives the second authentication information transmitted from the second authentication information transmission unit (904) and authenticates a user or user's right according to the second authentication information.
