Abstract
To provide a technology for making it possible to control enable/disable of an IC card function provided in a mobile device. A mobile device including an IC card unit for executing an IC card function, and a communication unit for carrying out communication through a radio telephone line detects a voltage of a battery unit for supplying an electric power to each of the IC card unit and the communication unit, judges whether or not the IC card function can be used in accordance with the detected voltage value, and issues an enable/disable instruction to the IC card unit in accordance with the Judgment results.
