  • Method for extending bar code PDF 417 coding capacities
    Patent number: 6942159
    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.
    Type: Grant

  • Method for extending bar code pdf 417 coding capacities
    Publication number: 20030127517
    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.
