Field: Digital communication (Electrical engineering)
Classification: CPC G  B  E  H | IPC G  H

Claim 9:
10. An in-vehicle device attached to a vehicle comprising a processor configured to:
perform authentication regarding a use of the vehicle;
cause a short-range communication module to perform short-range wireless communication with a ring-type wearable device that has a ring shape to be worn on a finger of a user, and has unique identification information; and
acquire information received by a wide area communication module configured to communicate, via a network, with a communication terminal configured to make a reservation for the use of the vehicle, wherein
the short-range communication module is located at a position at which a part of the vehicle operated by the finger of the user is included in a communication range of the short-range wireless communication of the short-range communication module,
when the communication terminal makes the reservation, the processor acquires, via the network, the identification information received by the wide area communication module from the ring-type wearable device through the communication terminal, and
when the short-range communication module performs the short-range wireless communication with the ring-type wearable device, the processor performs the authentication based on verification between identification information received by the short-range communication module from the ring-type wearable device and the identification information acquired by the processor.
