A polling processing unit executes a polling process for detecting a device that performs NFC communication. An NFC communication processing unit executes a communication process of performing NFC communication with a mobile device detected by the polling process. Power consumption associated with execution of the communication process is larger than power consumption associated with execution of the polling process. When authentication of the mobile device by an authentication processing unit is completed, or when the execution of the communication process continues for a prescribed time period, the NFC communication processing unit executes a stop process of stopping the communication process until the execution of the communication process is permitted.
