Hmm, seems my DL is already out of date. WI is switching to a new form of barcode: http://www.dot.state.wi.us/dmv/digital.html
License back contains information and new 2-D bar code
The fee paid for the product is indicated on the top of the card. The two-dimensional bar code on the back of the document is coded with information from the front side of the card. The 2-D Bar Code is more durable and secure than the previously used magnetic stripe. The anatomical Gift Statement is covered with a special ink-permeable plastic which allows customers to write on this portion of the card.
Looks like other states are doing the same thing. So much for erasing the mag strip. But I suppose it would be fairly easy to paint something over the barcode like some plastic disolving solvent, making it unreadable. -- Harmon Seaver, MLIS CyberShamanix Work 920-203-9633 Home 920-233-5820 hseaver@cybershamanix.com http://www.cybershamanix.com/resume.html
