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.

Cette invention concerne une carte de transaction financière (10) conçue pour permettre la lecture d'informations enregistrée de manière externe. Cette carte comporte une base rigide, sensiblement non pliable et transparente et une bande conçue pour stocker des informations exploitables par une machine (14). Ladite base rigide comporte une loupe (24). On forme cette dernière en usinant une cavité peu profonde (204) dans la base rigide; en remplissant partiellement cette cavité avec une résine liquide susceptible de durcir sous l'effet d'un rayonnement; en formant une structure de loupe (36) à la surface de la résine au moyen d'une matrice; et en exposant la résine à un rayonnement d'intensité suffisante pour durcir la résine.
