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. ## Claims ### Claim 1 A transaction card, comprising: a plurality of printable substrate layers; wherein at least one of the printable substrate layers comprises an infrared blocking material, the infrared blocking material comprising a quantum dot compound; and wherein the printable substrate layers are laminated together. ### Claim 2 (depends on 1) The transaction card of claim 1, wherein at least one of the printable substrate layers comprises a plastic polymeric substrate. ### Claim 3 (depends on 1) The transaction card of claim 1, wherein at least one of the printable substrate layers comprises polyvinyl chloride (PVC). ### Claim 4 (depends on 1) The transaction card of claim 1, wherein the printable substrate layers are transmissive to visible light. ### Claim 5 (depends on 1) The transaction card of claim 1, wherein the infrared blocking material comprises a mixture of a phosphor compound and the quantum dot compound. ### Claim 6 (depends on 1) The transaction card of claim 1, wherein the infrared blocking material comprises a mixture of a rare earth oxide compound and the quantum dot compound. ### Claim 7 (depends on 1) The transaction card of claim 1, wherein the infrared blocking material comprises an IR-absorbing compound. ### Claim 8 (depends on 1) The transaction card of claim 1, wherein the infrared blocking material comprises a mixture of two or more of the following: a rare earth oxide compound, the quantum dot compound, a phosphor compound, and an IR-absorbing compound. ### Claim 9 (depends on 1) The transaction card of claim 1, wherein the infrared blocking material comprises a mixture of at least two IR-absorbing phthalocyanine dyes. ### Claim 10 (depends on 1) The transaction card of claim 1, wherein the infrared blocking material is combined with a resin binder. ### Claim 11 A method of making a transaction card, comprising: forming an infrared blocking material on a first printable substrate layer that is transmissive to visible light, the infrared blocking material comprising a quantum dot compound; and laminating the first printable substrate layer together with one or more additional printable substrate layers to form a laminated transaction card, wherein the additional printable substrate layers are transmissive to visible light such that the laminated transaction card is transmissive to visible light. ### Claim 12 (depends on 11) The method of claim 11, wherein infrared blocking material is printed to the first printable substrate layer. ### Claim 13 (depends on 11) The method of claim 11, further comprising forming the infrared blocking material on both surfaces of the first printable substrate layer. ### Claim 14 (depends on 11) The method of claim 11, further comprising stacking the printable substrate layers together during lamination of the printable substrate layers. ### Claim 15 (depends on 11) The method of claim 11, wherein the first printable substrate layer is laminated between at least two of the additional printable substrate layers. ### Claim 16 (depends on 11) The method of claim 11, wherein at least one of the printable substrate layers comprises a plastic polymeric substrate. ### Claim 17 (depends on 11) The method of claim 11, wherein at least one of the printable substrate layers comprises polyvinyl chloride (PVC). ### Claim 18 (depends on 11) The method of claim 11, wherein the infrared blocking material comprises an IR-absorbing compound. ### Claim 19 (depends on 11) The method of claim 11, wherein the infrared blocking material comprises a mixture of two or more of the following: a rare earth oxide compound, the quantum dot compound, a phosphor compound, and an IR-absorbing compound. ### Claim 20 (depends on 11) The method of claim 11, wherein the infrared blocking material comprises a mixture of at least two IR-absorbing phthalocyanine dyes.
