ABSTRACT:
A security article comprises a substrate layer having a top surface and a bottom surface. The substrate layer is composed of an electrically nonconductive material. Deposited on the top surface of the substrate layer is a conductive thin film coating having a predetermined electrical resistance between two spaced apart points. In one embodiment, the conductive thin film coating is composed of a transparent conductive compound and has a thickness in a range between about 7 nanometers to about 700 nanometers. Printing can be positioned either on top of the substrate layer or on top of the thin film coating. An adhesive can be applied on the bottom surface of the substrate layer.
