Title:
非接触式ラベル内で特定機能を実現するためのシステムと方法
Document Type and Number:
Japanese Patent JP4354639
Kind Code:
B2
Abstract:
The invention concerns contactless electronic labels (10) associated with a reading device (40). The invention lies in the fact that the reading device (40) also comprises a generator generating sequences of pulses which characteristically modulate (50) a signal at a carrier frequency (F0), the modulation making it possible to code information to be transmitted to the electronic labels. These sequences of pulses are detected (22) and interpreted (26) by the electronic labels (10) and supply different signals which act on certain circuits in the electronic labels, in particular for inhibiting certain functions.
