The state of Iowa plans to release an app so residents with smartphones will be able to show their driver's licenses in a digital format - but the technology has a number of critics. Drivers won't be required to go digital, and it's unknown how the digital driver's license can be used on multiple phones.
There is concern of potential snooping when a citizen turns over his or her phone to an officer, but app designers are mulling over a locking feature that password-protects the phone from being accidentally unlocked.
"Not just anybody can download [the app]," said Mark Lowe, Department of Transportation director, told ABC News. "We need to know that after we have vetted you, you're the person accessing the app. A thumb print or fingerprint or facial recognition or voice or iris image. We have to change this static thing in your pocket to something that is live."
However, state officials believe it will provide a better identification format for officers, with a 3D image to better identify drivers. There is still no public timeline before the app will be released, with additional security testing being conducted.
