ABSTRACT:
A process for increasing the data encoding capacity of the PDF 417 bar code. After the data is compressed, the data is read by the data acquisition hardware which is linked to the scanning hardware connected to an information system. 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.
