Abstract
A non-opaque plastic card, having a first sheet layer with a front surface and a back surface, and a second sheet layer having a front surface and a back surface. A filter dye is located on the first sheet layer and/or second sheet layer, and allows visible light to pass through, while blocking infrared light from passing through the card. Graphical elements are printed on different surfaces of the card, with different combinations of backgrounds, to produce 3-dimensional effects.
