Provided are techniques for the placement of a code on an object that does not interfere and is not displayed in a captured visual image of the object. Also provided are techniques for capturing a first image of an object in the visual light spectrum; capturing a second image of the object in a non-visual light spectrum; extracting metadata, stored in the non-visual light spectrum corresponding to the object from the second image; and storing the first image in conjunction with the metadata. Also provided are techniques for storing the metadata in conjunction with the object in the non-visual light spectrum, wherein the metadata is stored in a quick response (QR) code or a bar code and the non-visible light spectrum is ultraviolet light or infrared light.
