Abstract
An information processing apparatus that improves the convenience of a user who performs authentication using an authentication medium. A communication system module acquires authentication information from an IC card. A sensor system module detects proximity of the IC card. A main circuit element group authenticates a user using the acquired authentication information. A power supply controller supplies power to those modules and the group. A power supply destination is controlled such that the apparatus is shifted to a power saving state in which power is supplied only to the sensor system module. In the power saving state, when the sensor system module detects proximity of the IC card, the power supply destination is controlled to cause the apparatus to shift to a normal power state in which power is supplied to the communication system module and the main circuit element group.
