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.

43. A method for making a transaction card which is at least in part substantially transparent to humanly visible light and which is detectable by card readers which use infrared light in connection with detecting the presence of such a card, said method comprising the following steps:
-
(a) forming a card core of transparent material; and
(b) applying a first infrared barrier layer to said core, wherein said first infrared barrier layer blocks infrared light in a first range of wavelengths; and
(c) applying a second infrared barrier layer to said core, wherein said second infrared barrier layer blocks infrared light in a second range of wavelengths. - View Dependent Claims (44, 45, 46)
