Further, in the vehicle keyless device according to the first embodiment, as shown in FIG. 3, when the non-contact type IC card 6 is put in the bag 9 together with the portable device 2 and gets into the vehicle, the IC card 6 is operated in particular. Even if it does not exist, the card payment which operated the telematics unit 8 which is a vehicle-mounted apparatus can be performed.
Since the non-contact type IC card 6 and the portable device 2 are in the bag 9, the IC card communication unit 28 of the portable device 2 communicates with the IC card 6, and the registration information of the IC card is stored in the reading memory 27. .

Then, at the time of communication for keyless processing, the information of the IC card 6 in the reading memory 27 of the portable device 2 is transmitted to the in-vehicle device 3 and stored in the IC card registration information unit 52 of the in-vehicle device 3.
For example, when there is a request for information for IC card settlement processing from the telematics unit 8 to the unit communication unit 53 of the in-vehicle device 3, the in-vehicle device 3 registers the registration information of the IC card 6 via the unit communication unit 53. Is sent to the telematics unit 8 and the payment processing unit 81 performs processing necessary for payment.
If processing necessary for payment is performed, communication for payment with the outside of the vehicle is performed by the payment communication unit 82 to complete the payment processing.

When there is the portable device 2 and the IC card 6 in the bag 9, there is a problem in crime prevention that payment can be made within the communication range with the in-vehicle device 3 even when the user is not on the bag 9. However, in the vehicle keyless device 1 of the first embodiment, it is confirmed that the portable device 2 is in the vehicle by determining which of the outdoor antennas 45 to 47 and the indoor antennas 48 to 50 communicates ( Step S4), settlement processing is performed only in that case.
Thereby, since the settlement process of the IC card 6 is performed when both the IC card 6 and the portable device 2 are in the vehicle, the crime prevention property can be improved.
That is, it is possible to prevent a third party from misusing the payment function of the vehicle keyless device 1.
