Claim:
1. An apparatus for reading information in a printed code containing at least one photo-responsive dye, the apparatus comprising: an electro-optical radiation emitter that emits radiation in a first wavelength band associated with an excitation frequency of the at least one photo-responsive dye; an electro-optical radiation detector that detects electro-optical radiation associated with a photo-response of the at least one photo-responsive dye during a code-reading operation; a processor that controls the emitter and detector; a memory portion that stores results collected by the detector; an interface that allows a user or downstream system to interact with the apparatus; and a position defining module that records time and global position information to associate a particular code to a location of the code-reading operation wherein the electro-optical radiation emitter triggers a holographic image-based code.
