Abstract

A process to extend the data encoding capacity using the PDF 417 bar code comprising a first step of compressing the data, the data being read by data acquisition hardware linked to scanning hardware connected to an information system, wherein the data is distributed using specific algorithms into a series of symbols that are dynamically linked to carry out a second compression, an element is introduced to control the integrity of the information and the formatting and reading of the data is controlled directly by the information system.

Claims

1. A process to extend the data encoding capacity using the PDF 417 bar code comprising a first step of compressing the data, the data being read by data acquisition hardware linked to scanning hardware connected to an information system, wherein the data is distributed using specific algorithms into a series of symbols that are dynamically linked to carry out a second compression, an element is introduced to control the integrity of the information and the formatting and reading of the data is controlled directly by the information system.

2. A data extension process according to claim 1, wherein the compressed data is distributed in packets of 1 KO, whatever their original volume.

3. A data extension process according to claim 1, wherein the data acquisition system and the application on reception of the data are integrated into the information system to which the reading hardware is connected.

4. A data extension process according to claim 2, wherein the data acquisition system and the application on reception of the data are integrated into the information system to which the reading hardware is connected.
