Abstract
A deactivatable tag useable with an electronic article surveillance system and method of making such a tag. The tag includes a resonant circuit and a provision for promoting the permanent deactivation of the tag. The solution according to the present invention has been to render the deactivator more difficult to operate. A higher level of excess energy is applied to the resonant circuit before the breakdown material breaks down. This higher level of energy in the resonant circuit is applied to the improved deactivator and operates the deactivator much more completely. This arrangement promotes permanent deactivation of the resonant circuit to prevent the resonant circuit from becoming active again or 'coming back to life' as time passes. The deactivator adjacent the resonant circuit can include a vacuum metalized conductive coating.
