An Electronic Article Surveillance ("EAS") tag and method and system for deactivating EAS tags without the need to physically contact the tag with a deactivation device. The EAS tag replaces the conventional diode with a non-linear device such as a metal-oxide-semiconductor ("MOS") capacitor with a given breakdown voltage threshold. Inducing a predetermined voltage across the MOS capacitor results in destruction of the MOS capacitor rendering the EAS tag undetectable in the EAS interrogation system.
L'invention porte sur une étiquette de surveillance électronique d'article (EAS) et sur un procédé et un système pour désactiver des étiquettes EAS sans nécessiter un contact physique de l'étiquette avec un dispositif de désactivation. L'étiquette EAS remplace la diode classique par un dispositif non linéaire tel qu'un condensateur métal-oxyde-semi-conducteur (MOS) ayant un seuil de tension de claquage donné. L'induction d'une tension prédéfinie aux bornes du condensateur MOS entraîne une destruction du condensateur MOS rendant l'étiquette EAS indétectable dans le système d'interrogation EAS.
