Police in the UK have started using a mobile fingerprinting system that lets them check the identity of an unknown person in less than a minute. Fingerprints collected on the street will be compared against the 12 million records contained in national criminal and immigration fingerprint databases and, if a match is found, will return the individual’s name, date of birth and other identifying information.

Officers will only resort to fingerprint scanning if they cannot identify an individual by other means, says Clive Poulton, who helped manage the project at the Home Office. The devices might be used in cases where someone has no identifying information on them, or appears to be giving police a fake name. “[Police] can now identify the person in front of them – whether they are known to them or not known to them, and then they can deal with them,” Poulton says.
