FIELD: information technology.
SUBSTANCE: disclosed method employs radio frequency labels, a scanning device and phase-shift keyed composite signals. The apparatus which realises the disclosed method comprises a vehicle (1), an alphanumeric code (2) consisting of eight characters, a sandblasting gun (3), a labelled element (4), a safety marker (5), a scanning device and a radio frequency label. The scanning device includes a UV radiation source (6), a first (7) and a second (11) power amplifier, a high frequency harmonic source (8), a duplexer (9), a transceiving horn antenna (10), a phase detector (12) and a digital display (13). The radio frequency label has a piezoelectric crystal (14), a microstrip transceiving antenna (15), electrodes (16), buses (17), (18) and a set (19) of reflectors.
EFFECT: invention increases reliability of protecting vehicles from unauthorised access.
