METHOD FOR MAKING A WALLET CARD WITH AN INTEGRAL MAGNIFYING LENS |
| 摘要 |
A wallet card (10) adapted for use in reading externally stored information includes a transparent, substantially non-foldable semi-rigid base (202). The semi-rigid base comprises a magnifying lens. The lens is formed by heating a lens forming die (210) to a temperature sufficient to soften the base material and then cooling the die prior to withdrawing the die from the base material. |
