For all the recent talk of moving to digital wallets, you can't really ditch the old-school kind yet -- you still need to carry physical copies of your driver's license and other forms of ID. If you live in Delaware, though, you may eventually have one less reason to worry when you leave your purse or wallet at home. The state's Senate recently passed a resolution asking the Division of Motor Vehicles to research a digital driver's license that you would store in an app on your phone. While many of the details still have to be worked out, you'd use some kind of biometric security (such as your face, fingerprint or voice) to get access on top of a code. There's no timetable for when Delaware would test these licenses, but it may not take long given that the state's development partner, MorphoTrust, has been working on the technology for a while.
