DES MOINES (AP) — Police in Des Moines and Sioux City will soon be using license plate-scanning technology to determine whether tags are expired or if the vehicle’s owner is linked to an arrest warrant.

The technology includes cameras on patrol cars that can instantly process license plates and tag each file with the date, time and GPS location for later reference, The Des Moines Register reported Monday.

The program debuted in Iowa in Polk County last year. It will expand to Sioux City in about a month and to Des Moines this fall.
