As I was surfing the various news sites I ran across this CNN article.

(CNN) -- It seems not too long ago that the highest tech device that a bouncer may have had was a flashlight to check out a driver's license. But these days, more and more bars and night clubs, convenience stores and liquor stores are using high-tech ID scanners in order to look at the information that's actually embedded in many driver's licenses.
I don't necessarily have a problem with people being able to read the magnetic strip on the back of my driver's license, but I do have a problem with the potential ability to store that information.
