DES MOINES, Iowa (AP) — Iowa bartenders and police officers want to know more about how the state’s new digital driver’s licenses will work when they reach smartphones next year. The Des Moines Register reports officials haven’t yet explained how bars and retailers will be able to verify the ages of customers when they want to buy alcohol.

Mark Stringer with the American Civil Liberties Union of Iowa says he wants to know more about what limits will be in place to keep officers from searching someone’s smartphone while they look at the digital license.

State Transportation Director Mark Lowe says the questions about the new licenses should be addressed before they debut around the middle of next year.
