Abstract
A system includes a multiplexed optical identifier and a reader for the optical identifier. The multiplexed optical identifier includes an optical substrate, and a plurality of volume holograms in the optical substrate. The reader includes an illumination source and a camera. The illumination source is configured to direct light into the optical identifier to produce an image of a corresponding one of the volume holograms at the camera, and the camera is configured to capture the image, which is stored in a digital format by the system. The multiplexed optical identifier contains more than one code page, wherein each of the code pages is used for a different purpose.
