Abstract
An electronic device includes: a card reader into which a card is inserted and which reads out information carried on the card; a power supply unit which supplies power to the card reader; a detection unit which detects the insertion of a card into the card reader and the ejection of a card from the card reader; and a control unit which controls the power supply unit. When the detection unit detects the insertion of a card, the control unit causes the power supply unit to start the supply of power to the card reader, and when the detection unit detects the ejection of the inserted card, the control unit causes the power supply unit to shut off the supply of power to the card reader.
