ELECTRONIC EQUIPMENT SYSTEM, ELECTRONIC EQUIPMENT AND MEMORY MODULE

摘要

PROBLEM TO BE SOLVED: To surely prevent a memory module from being accessed illicitly. SOLUTION: In a radio terminal 1, when a user requests an IC card 2 to be extracted, an extraction authentication processing part 17 authenticates the user. A card lock mechanism part 16 locks the IC card 2 until the authentication turns out to be confirmed. When the authentication is confirmed, the effect that the authentication is confirmed in notified from the radio terminal 1 to the IC card 2. When the IC card 2 is extracted from the terminal 1 while the authentication is not confirmed, an IC card controlling part 21 processes information so that the contents of the information stored in a memory part 22 can not be looked at in the IC card 2.
