<p>The invention concerns contactless electronic labels (10) associated with a reading device (40), characterised in that the reading device (40) further comprises a generator of pulse sequences which characteristically modulate (50) a carrier frequency signal (F0), the modulation enabling to encode data to be transmitted to the electronic labels. Said pulse sequences are detected (22) and interpreted (26) by the electronic labels (10) and supply different signals which act on certain circuits of the electronic labels, in particular to inhibit certain functions.</p> |
