In a bold move, Iowa will pilot a smartphone driver’s license program in 2015. The Iowa Department of Transportation will give users the option to download a free app to obtain the digital license — essentially "an identity vault" — and it will be accepted by Iowa law enforcement officers during traffic stops and by security officers screening travelers at Iowa's airports. The app will require a pin number for verification. Officials believe that Iowa will be the first state in the nation to implement such a device. Iowa is also already one of 30 states that let drivers display electronic proofs of insurance during a traffic stop.
