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