Transaction card
View Patent ↗The present invention relates to a process for producing a transparent or translucent transaction card having multiple features. An optically recognizable compound may be associated with a portion of the card for blocking infrared radiation and may comprise an infrared ink having nanocrystalline indium tin oxide particles. Moreover, a portion of the transaction card may include a second optically recognizable compound disposed thereon. The second optically recognizable compound may comprise an infrared phthalocyanine dye, an infrared phosphor, and a quantum dot energy transfer compound. The infrared ink may be detected by a sensor found in an ATM or card assembly line.
