Maryland has launched its pilot program for a phone-based digital driver's license.
The state's transportation department said in a statement Thursday that volunteers are working with various institutions and businesses to test out the IDs.
The state said the app will serve as a secure companion to physical IDs. They're also more private. Digital driver's license holders only have to display the information required in a particular situation.
The state is collaborating with the Maryland company Gemalto. The program is a two-year effort funded by the National Institute of Standards and Technology.
