ABSTRACT:
An electronic communication system for a vehicle, including a base station which is accommodated in the vehicle and at least one portable data carrier which is arranged to exchange data signals with the base station. A first coupling link is formed at least partly by the body of a user, whose skin is not required to be in physical contact with the data carrier, so that the body of the user contactlessly conducts displacement currents from the data carrier without contacting the data carrier. This permits the user to unlock a car door, or trunk, and/or start the vehicle, without using a key or having to touch a remote control device. The data carrier can be located in a briefcase and/or purse, and the ability to access the vehicle is not comprised even though there is no physical contact between the user and the data carrier.
