Abstract:
1. A mobile radio communication device for transmitting/receiving data to/from an external radio communication apparatus located in an area that allows radio communication, the mobile radio communication device including: a radio-signal transmitting/receiving unit for performing radio communication with the external radio communication apparatus; a connection unit detachably connected to an IC card that receives power supply from the mobile radio communication device, that manages data transmitted/received to/from the external radio communication apparatus, and that manages a communication mode state of the mobile radio communication device; radio-signal strength determining means for determining whether or not a strength of radio signals received from the external radio communication apparatus is less than or equal to a preset threshold value; and IC-card-mode initializing means for resetting a mode of the IC card to an initial state when the radio-signal strength determining means determines that the strength of the received radio signals is less than or equal to the threshold value.
