The device has a radio frequency identifier (1) that is carried by a driver of a vehicle and that transmits a radio frequency information towards a radio frequency receiver (2). The receiver allows engine of stolen or displaced vehicle to stop its operation (2.5) and generates a visual alarm (2.6) and siren (2.7), when the receiver stops receiving the information from the identifier due to displacement of the vehicle outside a delimited zone. |
