Abstract
A wallet card adapted for use in reading externally stored information includes a transparent, substantially non-foldable semi-rigid base. The semi-rigid base includes a magnifying lens. The lens is formed by heating a lens forming die to a temperature sufficient to soften the base material and then cooling the die prior to withdrawing the die from the base material.
