In a mobile terminal, a control section (7) monitors a battery residual amount at a power supply section (8), if the battery residual amount is less than a preset threshold, it refers to the states of various flags stored in a flag table at a memory section (4). Subsequently, if the control section judges it is before exit after entry for a service for the object of a lock temporary release and an entry and exit usage service, it changes a noncontact IC card function section (3) to a lock temporary release state. This allows the noncontact IC card function to be in a lock temporary release state, just before the power supply is turned off, even if the battery residual amount is low. Therefore, when the commuter gets off a train and passes through a station ticket gate, the commuter may use the noncontact IC card function. |
