The identifier exchanges digital information at a distance in a car. The identifier has a magnetic field receiver coil (6) forming a loop antenna and a central support (9). There are a number of electrical components (12). The central support has a holder (11) holding the electrical components. The central section is made of a magnetic material channeling the magnetic field lines away from the metallic earth formed by the electrical components.
