Abstract

A financial transaction card is transparent or translucent to human viewing yet detectable by automated card processing equipment. The card includes a substantially planar material sheet having upper and lower surfaces bounded by a continuous peripheral edge. The material sheet has one or more areas that are at least minimally transparent or translucent to human viewing. A filter associated with at least one of the areas provides sufficient opacity to light used by card sensors in the automated card processing equipment to render the card detectable.

Claims

1. A financial transaction card that is transparent or translucent to human viewing yet detectable by automated card processing equipment having near Infrared source/detector pairs, each source/detector pair including a near Infrared light source and a near Infrared light detector respectively positioned to face opposing sides of said card when said card is positioned in said equipment for detection and to detect said card by sensing an interruption of near Infrared light transmitted from said source to said detector due to the presence of said card, comprising:

a substantially planar material sheet having upper and lower surfaces bounded by a continuous peripheral edge;

said material sheet having an area that is at least minimally transparent or translucent to human viewing and located so as to span an optical pathway of one or more of said source/detector pairs when said card is positioned in said equipment for detection; and
