What is that data? how to read, modify and create new same looking pdf417 barcode?
It is a string for the DL data. You must be reading a sample as there is no data in it.
ie - DCSLASTNAME = DCS is the "header" for last name - then the next XXX character should be the last name that is on the license.
Research will take you here: https://www.aamva.org/FL-ITN-DriverRelatedCredentialPrintSolutionExh3-022016/ for the standard and how to parse the data out of the DL barcode.
