Beschreibung
Zusammenfassung:	A device comprising: an optical emitter for emitting light having an emitted optical spectrum; an optical sensor for receiving light reflected from a tag attached to an object; and a processor configured to: determine a reflected optical colour spectrum of the light reflected from the tag based on an output of the optical sensor; retrieve an optical signature associated with said object from memory; and determine the authenticity of said object based on comparing the optical signature and the reflected optical colour spectrum.
