CA 2410493

The invention concerns a method for extending PDF 417 bar code data coding capacities comprising a first data compression step, the data being read by an acquisition equipment linked to a reading equipment connected to an information system. It consists in distributing the data by means of specific algorithms into a series of dynamically related symbols and in controlling data formatting and reading directly from the information system.

L'invention concerne un procédé d'extension des capacités d'encodage de données à l'aide du code à barres PDF 417 comprenant une première étape de compression des données, les données étant lues par un matériel d'acquisition en liaison avec un matériel de lecture connecté à un système d'information. On répartit à l'aide d'algorithmes particuliers les données en une série de symboles liés dynamiquement et on commande le formatage et la lecture des données directement à partir du système d'information.
