Police to use facial recognition at Champions League final

Police in Wales plan to use facial recognition on fans during the Champions League final in Cardiff on 3 June, according to a government contract posted online. Faces will be scanned at the Principality Stadium and Cardiff's central railway station. They can then be matched against 500,000 "custody images" stored by local police forces. South Wales Police confirmed the pilot and said it was a "unique opportunity". A report on the plan was first posted by tech news site Motherboard.
