MultiTaction Codice is software using optical markers and objects for recognizing individual users and accessing personalized content. The display recognizes and identifies optical markers using computer vision and object recognition algorithms. The Codice optical marker is similar to a QR code, which is itself basically a more developed version of a traditional bar code. By placing an optical marker on a display, a user can quickly show, play, send and receive personalized and exclusive content, resulting in a highly personalized digital signage experience. Customer transactions can be recorded in order to provide the content owner with a real-time view of their clients’ interests. Codice turns anonymous public interactive displays into personal two-way tools that benefit the user and the content owner. It is based on MultiTouch’s proprietary Enriched Reality technology. 2D bar codes can be printed on any object such as cell phones, tickets, loyalty program cards or visitor badges. They can even be printed at home and used with any Codice-enabled interactive display. The uniqueness of Codice optical markers is controlled by the MultiTouch DRM Server, which guarantees that the same code is never in use by more than one person. MultiTouch DRM Server has a capacity for over four billion unique codes.
