Codentify is a product serialization system developed and patented in 2005 by Philip Morris International (PMI) for the verification of authenticity and production volume, as well as supply chain control of tobacco products. In the production process, each cigarette package is marked with a unique visible code (also called “Codentify”), that allows authenticating the code against a central server.
In November 2010, PMI licensed this technology to its three main competitors, namely British American Tobacco (BAT), Imperial Tobacco Group (ITG), and Japan Tobacco International (JTI), and the four companies together formed the Digital Coding and Tracking Association (DCTA) which works to promote the system in order to replace governmental revenue stamps. Codentify was branded by its inventors as a “track & trace and product authentication technology”.
