<p>A financial transaction card (10) adapted for use in reading externally stored information includes a transparent, substantially non-foldable rigid base and a strip for carrying machine readable information (14). The rigid base comprises a magnifying lens (24). The lens is formed by machining a shallow cavity (204) in the rigid base; partially filling the cavity with a radiation curable liquid resin; impressing a lens pattern (36) on the surface of the resin with a die; and exposing the resin to radiation of sufficient intensity to cure the resin.</p> |
