Abstract
The invention is a transaction card having a base comprising a core of substantially transparent material with a plurality of coats, on at least one of the core's surfaces, of a material which is substantially transparent to humanly visible light and which is opaque to light in the infrared portion of the light spectrum. The invention is also a method for manufacturing a transaction card having an area which is substantially transparent to humanly visible light and which may be detected by card readers, such as ATMs and card printers. The method includes the steps of forming a core of substantially transparent plastic and applying a plurality of coats of material to at least one surface of the core, which material is substantially transparent to humanly visible light and which is opaque to light in the infrared portion of the light spectrum.
