Abstract
Described are a system and a method for anti-counterfeit barcode labels. The system may include an automatic identification symbol reader obtaining item data and a first spectral signature data; a spectral signature reader obtaining a second spectral signature data from a spectral signature; and a processor for decoding and validating a automatic identification symbol as a function of a comparison of the first spectral signature data and the second spectral signature data.
