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.
Claims20
A subassembly for use in a transaction card, said subassembly comprising:
- at least one of a translucent and transparent subassembly surface incorporated into a card;
- and a machine recognizable compound containing an infrared blocking material associated with and substantially covering said surface, wherein said infrared blocking material comprises an infrared blocking film comprising a plurality of layers disposed on a substrate, said plurality of layers comprising at least two layers having different refractive indices.
An article, comprising:
- a subassembly comprising at least one of a translucent and a transparent surface;
- and
- a machine recognizable compound containing an infrared blocking material associated with, and substantially covering, said surface, wherein said infrared blocking material comprises an infrared blocking film comprising a plurality of layers disposed on a substrate, said plurality of layers comprising at least two layers having different refractive indices, wherein said article is a card.
A method of making an article, comprising the steps of:
- providing a subassembly comprising at least one of a transparent and a translucent surface;
- and
- associating a machine recognizable compound containing an infrared blocking material with the subassembly, wherein said infrared blocking material is comprises an infrared blocking film comprising a plurality of layers disposed on a substrate, said plurality of layers comprising at least two layers having different refractive indices, and incorporating said subassembly into a card.
A subassembly for use in an article, said subassembly comprising:
- at least one of a translucent and transparent subassembly surface incorporated into a card;
- and
- a machine recognizable compound containing an infrared blocking material associated with and substantially covering said surface, wherein said infrared
- blocking material comprises an infrared blocking film comprising a plurality of layers disposed on a substrate, said plurality of layers comprising at least two layers having different refractive indices.
A subassembly for use in an article, said subassembly comprising:
- at least one of a translucent and transparent subassembly surface incorporated into a card;
- and a machine recognizable compound containing an infrared blocking material associated with and substantially covering said surface, wherein said machine recognizable compound has a thickness of less than about 50 microns and further
- wherein said infrared blocking material thereof comprises an infrared blocking film comprising a plurality of layers disposed on a substrate, said plurality of layers comprising at least two layers having different refractive indices.
