Abstract
A mobile device wirelessly communicates with a vehicle device. The mobile device includes a receiving unit, a response signal generation unit, a transmission unit, a charging unit, and a charge state determination unit. The receiving unit receives a response request signal transmitted from the vehicle device. The response signal generation unit generates a response signal in response to the response request signal. The transmission unit transmits the response signal. The charging unit charges a built-in battery with an electric power supplied wirelessly or through wire from a power supply device. The charge state determination unit determines whether the charging unit charges the built-in battery. The mobile device is configured not to transmit the response signal, in a situation where the charge state determination unit determines that the charging unit is charging the built-in battery.
