New technology allowing police to take fingerprints at the side of the road will be used by officers in Northumberland.
A mobile fingerprint terminal linked to the national fingerprint database will let motor patrol officers confirm the identity of people they stop.
The machine scans a subject's index finger before transmitting it to the central database using an encrypted wireless system.
Officers can have the results within minutes, and all fingerprints are deleted from the terminal at the end of the shift.
Chief Inspector Simon Packham of Northumberland Police said: "Mobile fingerprint terminals give police officers the ability to take fingerprints on the street away from the police station.
"This reduces the need to arrest or detain people at police stations for identification purposes so it is more efficient for the force and more convenient for the person stopped."
