Patent ID: 7653919

Claim:
An optical article that can transform from a pre-activated state of functionality to an activated state of functionality, comprising: an optical data layer for storing data, wherein said data is read from said optical data layer in said activated state of functionality; a radio frequency circuitry coupled to the optical article; an external radiation source for generating an external stimulus which interacts with the radio frequency circuitry to produce a signal, wherein said signal comprises a thermal signal, an electrical signal, or both; wherein the radio frequency circuitry is disposed on a detachable label; wherein said detachable label has an adhesive disposed thereon, wherein a bond strength of said adhesive can alter upon interaction with the external stimulus, wherein said detachable label is coupled to the optical article and being responsive to said external stimulus, said detachable label being in optical communication with said optical data layer for altering the optical article from the pre-activated state of functionality to the activated state of functionality upon interaction with said external stimulus; a convertible material in operative association with said radio frequency circuitry; and wherein said convertible material comprises an adhesive, a color-shift dye, a photovoltaic material, a magnetic material, a magneto-optical material, a phase-change material, dye aggregates, nanoparticles or combinations thereof.
