Metropolitan Police Service has signed a £18.1 million deal with IT services company Detica for mobile devices.
Under the contract, Detica will supply and manage operational PDAs, mobile data terminals and associated infrastructure over the next five years.
Police are piloting a scheme to give officers on the beat access to a central database of fingerprints, mugshots and data on criminal suspects through mobile devices.
Police could use hand-held computers to take fingerprints and view a national database of criminals' mug shots by the time of the 2012 London Olympics, Peter Neyroud, chief executive of the National Policing Improvement Agency, told MPs at a final session of a home affairs committee inquiry into 'The Surveillance Society'.
Detica and the Metropolitan Police would not provide any more details about the deal.
