CREDIT CARD WITH MAGNIFYING LENS |
摘要 |
A credit card (10) includes an integral magnifying lens (24) 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 (14) and the embossed indicia (12) associated with the card is not impaired. The magnifying tens (24) incorporates a fresnel-type contour lens (36) mounted in a window (25) provided in the credit card base. |
