Abstract
A composite security device is provided that is made up of a first polymer film that constitutes or embodies a security feature in the form of at least one high value material, and a second polymer film that constitutes, embodies, or is coated with one or more additional security features. The first polymer film is positioned on and adhered to a surface of the second polymer film, which has a width or diameter greater than the width or diameter of the first polymer film By way of the present invention, the high value material is applied to only a part of the security device, leaving remaining parts of the device available for one or more additional materials that do not impact upon the effect of the high value material.
