This document enables reading the PDF417 barcode on the back of many USA driver's licenses. The WDI4700 should be able to read this off a computer monitor. If you have trouble, print the page out and scan that.

Note that due to the amount and complexity of data contained in the barcode, there is not a way for the scanner to parse and output specific pieces of information. However, the data is formatted in such a way as to identify various pieces of information, and parse that in a custom program or something like Excel that uses formulas.
Below is an example of the data contained in the barcode in a Texas driver's license (including non-printable characters).
