Abstract
A system for decoding machine-readable graphical codes is provided. The system includes a graphical code reading device configured to read a graphical code and generate reference encoded source data. The reference encoded source data includes a first reference identifier and a second portion. The system also includes a computing device in electronic communication with the graphical code reading device. The computing device also includes a reference decoder configured to effect conversion of the reference encoded source data into source data. The source data includes first affiliated data in place of the first reference identifier. The first affiliated data may be longer in length than the first reference identifier. The source data also includes the second portion. The computing device also includes a software application configured to use the source data.
