Abstract:
1. A tamper resistant electronic tag, comprising: a protective card; an integrated circuit attached to the protective card; a first substrate layer having a first side and a second side retaining a first electronic element, wherein the first side of the first substrate layer is arranged to be adhered to a surface by a first adhesive layer, and a first portion of the second side of the first substrate layer is adhered to the protective card by a second adhesive layer; and, a second substrate layer having a first side and a second side retaining a second electronic element operatively coupled to the first electronic element, wherein the first side of the second substrate layer is adhered to a second portion of the second side of the first substrate layer by a third adhesive layer, and the second electronic element is operatively attached to the integrated circuit; wherein the first adhesive layer is stronger than the second adhesive layer, and the third adhesive layer is stronger than the operative attachment between the integrated circuit and the second electronic element; wherein said first and second electronic elements form a passive circuit component and when, said first substrate layer is attached to said surface by said first adhesive layer, an attempt to remove the tag from said surface results in at least one of: said integrated circuit becoming operatively detached from said second electronic element, or said second substrate layer becoming separated from said first substrate layer so as to damage said operative coupling between said first and second electronic elements, damaging said passive circuit component.
