An electronic card having an electronic control circuit, an elector-optical element configured as a normal operation indicator, and a power supply source. Electrical tracks connect the electronic control circuit with the electro-optical element and the power supply source, and affixing elements attach the electronic card to a substantially planer surface. The electrical tracks having embrittlement grooves which destroy the connections made by the electrical tracks upon removal of the electronic card from the substantially planer surface to which the electronic card is attached. The electronic card is suited for applications in the identification and automatic detection of objects and in particular, stolen vehicles.

Electronic card with indicator of normal operation

A system for the identification and automatic detection of vehicles or objects includes an electronic label installed in each of the vehicles or objects, each of these electronic labels having means for memorizing an identification code assigned to a vehicle or object in which the electronic label is installed and radioelectrical transmission and reception means for transmitting this identification code, and at least one mobile reader disposed exterior to the vehicles or objects and movable within a vicinity of these vehicles or objects. Each mobile reader includes a recording memory for recording a file of identification codes of vehicles or objects to be identified, radioelectrical means for transmitting a signal to at least one of the vehicles or objects which prompts the electronic labels of these vehicles or objects to transmit identification codes assigned to these vehicles or objects to the radioelectrical means, comparison means for comparing the identification codes recorded in the file of the recording memory with each identification code transmitted by the electronic labels, and reporting means for reporting to authorities the presence of any vehicle or object whose identification code appears in the file of the recorded memory, as determined by the comparison means. The invention finds particular utility in the automatic detection of stolen vehicles, the purchase of second hand vehicles, and identity checks on motorists.
