A first unit A stores the identity of equipment (e.g. vehicle) to which the unit is attached and transmits it in scrambled digitally coded form to a second unit B (e.g. hand-held) which unscrambles it and compares the identity with a database of identities (stolen equipment) and actuates a display in the event of a match. The system enables a vehicle to be stopped. |
