摘要：
An NFC device according to the present invention includes the following units. An antenna unit receives radio waves from a reader/writer by NFC. A first power source unit generates power from the radio waves. A second power source unit is a drive power source. A power-supply state holding unit holds information indicating a power-supply state of the second power source unit. An NFC unit performs NFC via the antenna unit to transmit the information indicating the power-supply state of the second power source unit. A power source switch unit switches the second power source unit to the first power source unit according to the power-supply state of the second power source unit, in order to supply power to activate at least the NFC unit and the power-supply state holding unit.
