Claim Text:
1. An identification medium configured for displaying visible and excitable indicia, comprising: a substrate having a print displaying layer wherein the print displaying layer comprises a direct thermal or color change layer configured to accept and display the visible indicia in response to thermal energy pulses from a thermal printer, wherein the direct thermal or color change layer is itself insensitive to or insoluble in solvents used with excitable inks; an excitable layer comprising excitable ink forming the excitable indicia, said excitable layer overlying the print displaying layer, wherein the excitable indicia is printed separately from the visible indicia; and wherein the excitable ink exhibits luminescence when exposed to directed radiation, and the excitable ink is configured to generate a higher emitted intensity of a readable spectrum of light as compared to the print displaying layer when both are exposed to the directed radiation.
