Abstract
Abstract A card having an information upon which information appears that can be read in the normal manner; a portion carrying a microfilm upon which information is recorded and a portion carrying a lens suitable for reading the microfilm. The card comprises a paper card having an aperture formed in one end region in which is located the microfilm. A pair of flexible clear plastic sheets laminate opposite sides of the paper card including the microfilm. A lens aperture is formed through the clear plastic sheets and through the paper card at an end region opposite the microfilm. A round plastic lens is located in the lens aperture. The lens comprises a central magnifying portion and an outer rim having an outer annular flange. The outer rim is higher than the surface of the central magnifying portion on each side thereof for providing protection for the central magnifying portion of the lens. The lens is secured in the aperture either by ultrasonic welding or by adhesive.
