Finding Pay Dirt in Scannable Driver’s Licenses — another outrage. I wonder if you get to patronize the business if you insist on being ‘carded’ in the old way, with a visual inspection of the data on the front of the card instead of letting it be swiped in. I object to this for the same reason I don’t use the preferred-customer discount cards at grocery stores and drugstores unless they will agree to issue me one under a pseudonym. If swiping in the driver’s license gets to be a more widespread practice, what would be the downside to taking a penknife [or, as a reader suggested, a strong magnet, although the visible defacement of the card serves a civil disobedience purpose… –FmH] to the magnetic strip on the rear to prevent its data being readily harvested in the swipe?
