Self-Authenticating Blister Pack

Tablets from micro-structured stamps are randomly transported into blisters creating a natural random code which is encrypted and recorded in the printed 2D Barcode on the carton.

To authenticate a blister taken from a carton, the 2D barcode on the carton is first scanned using a special smart-phone app.  Using the same app, the tablets are photographed and an algorithm checks the information in the barcode against the information retrieved from the tablets.
