Officers on the beat in Aberdeen will be using the mobile fingerprint scanners which it is claimed will free up several hours of police time.
The innovative scanners are linked to a national fingerprint database and instantly alert police if the scanned prints belong to a convicted criminal.
The hand-held device can also pinpoint where there is a real cause for concern for a person. This may include someone who is heavily drunk and too intoxicated to give their names and addresses, but are in need of urgent medical help.
Chief Inspector Nick Topping, Area Commander North, said: "The mobile fingerprint scanners will be of great benefit to officers across the Granite City, as they have the real potential to free up police time by providing quick and early identification of an individual and allow officers more time on the street, working within their local communities.
"It can be a considerable impact on our time to have to convey people to a police station in order to confirm their identification where there may be dubiety.
"The mobile scanners can quickly confirm this and ultimately, free up officers to be on the streets protecting the public.
"It will also ensure that members of the public who we need to speak to in relation to our inquiries are not unnecessarily delayed in going about their own business.
"The scanners will also provide opportunities for police to detect the small minority who may attempt to pervert the course of justice by providing false details."
