Illinois was one of the few states to encrypt its drivers licenses, and as of May 2013 they stopped this practice.
In an email from the Illinois Secretary of State they wrote: "Since the information contained in the 2D barcode prints on the front of the card, the office made the decision to allow access. It allows other states, retailers and similar users to verify that the information on the face of the card has not been altered."
This is a great move and will prevent "chalking" a drivers license to change the information. Good work Illinois!
