Abstract (en)
[origin: US6414596B1] The present invention relates to a security element for electronic article surveillance, comprising two at least partially overlapping layers of conductor strips interconnected by a dielectric adhesive coating. This arrangement reduces the risk of reactivation after activation is once effected. To achieve this, the upper layer and the lower layer of conductor strips have at least one turn, and that the strength of the two layers of overlapping conductor strips is so high as to cause the security element to bend, if subjected to mechanical strain, in those areas which are essentially devoid of conductor strips.
