Abstract: In an arrangement for marking of vehicles to hinder theft or unauthorized sale, the marking permanently applied to the vehicle comprises a multiplicity of microscopic information carriers having data (secondary information) encoded thereon which data normally coincides with information providing details on the identity of the vehicle (primary information) stored in some other way and not accessible to manipulation. Many thousands of information carriers encoded with the secondary information are incorporated in the manner of pigments into a vehicle coating, at least at certain locations.
