Abstract

The present invention relates to a process for producing an opaque, transparent or translucent transaction card having multiple features, such as a holographic foil, integrated circuit chip, silver magnetic stripe with text on the magnetic stripe, opacity gradient, an invisible optically recognizable compound, a translucent signature field such that the signature on back of the card is visible from the front of the card and an active thru date on the front of the card. The invisible optically recognizable compound is an infrared ink and/or film, which can be detected by a sensor found in an ATM or card assembly line.

Claims
