Credit card with magnifying lens
A credit card includes an integral magnifying lens positioned in the non-data area on the credit card for permitting magnification of the credit card transaction form at the point-of-sale. The placement of the lens assures that the machine readability of the magnetic encoding strip and the embossed indicia associated with the card is not impaired. The magnifying lens incorporates a fresnel-type contour lens mounted in a window provided in the credit card base.
