Abstract
A password corresponding to an IC card or a service is stored or registered in a terminal apparatus provided with a preferably contactless IC card section having a read/write function. A password is inputted before utilizing the IC card function. The IC card function, which is disabled for utilization under other conditions, is enabled for utilization during a period of time only when the inputted password matches the registered password, thus even when the device is lost or stolen, others cannot have access to the services available for the apparatus without authentication.
