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 preferably an infrared ink comprising an infrared phthalocyanine dye, an infrared phosphor, and a quantum dot energy transfer compound. The infrared ink can be detected by a sensor found in an ATM or card assembly line.

La présente invention concerne un procédé pour produire une carte de transaction opaque, transparente ou translucide possédant de multiples particularités, telles qu'une feuille holographique, une carte de circuit intégré, une bande magnétique argentée comportant du texte, un gradient d'opacité, un composé invisible optiquement reconnaissable, un champ de signature translucide permettant à la signature au verso de la carte d'être visible sur le recto de la carte et une date d'expiration active portée au recto de la carte. Le composé invisible optiquement reconnaissable est, de préférence, une encre infrarouge comprenant une teinte phtalocyanine infrarouge, une substance fluorescente infrarouge et un composé de transfert d'énergie à point quantique. L'encre infrarouge peut être détectée par le capteur d'un guichet bancaire automatique ou d'une chaîne d'assemblage de carte.
