This is demo of some code that I've written in VB6 to read and parse the 2D barcode on the back of a Drivers license. It has been tested with licenses from NY, NJ and CT. I believe it will work with other states. I have tested it with E-Seek mode 200 and 250 as well as the Symbol VS4000 keyboard wedge (not such a good reader, though.) It does the standard fields only, but it can be modified to extract the extra fields that some states use.
Download the exe file and save it to a test directory. I don't think the operation requires much explanation. You have to use the config screen to indicate keyboard wedge or serial port. The code originally had a database update which is I removed from the code for the demo.
I can modify this in a few minutes for use with a flat file or an ODBC database.
