CA 2330321

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.

L'invention concerne une carte pour portefeuille (10) adaptée pour permettre la lecture d'informations mémorisées de l'extérieur, la carte comprenant une base (202) semi-rigide, transparente et sensiblement non pliable. La base semi-rigide comprend une lentille grossissante. On forme la lentille en chauffant un moule (210) de formage de lentille à une température suffisante pour adoucir la matière de base, puis en refroidissant le moule avant de retirer le moule de la matière de base.
