ABSTRACT:
A field-sensitive tag or label incorporates a layer for mechanically deactivating the tag resulting from subsequent use of the article to which the tag has been applied. To this end, a layered tag is provided which, in addition to the layers which are traditionally provided to achieve the function of a resonant circuit (e.g., substrate and etched outer layers), further incorporates a circuit-deactivating layer which preferably takes the form of an abrasive substance disposed in a suitable binder. The resulting layer can then operate to mechanically deactivate the tag by damaging at least a portion of the resonant circuit which comprises the tag due to movement of the article in subsequent use. The field-sensitive tag of the present invention is advantageously applied to footwear in regions where flexure of the tag can be anticipated, preferably in the sole, making the article well suited to placement in a self-service retail setting while maintaining an adequate degree of security.
