Champions League final fans to have faces scanned

Police in Cardiff will use facial recognition to track the 170,000 football fans expected to descend on the city for the Champions League final. The Welsh capital is gearing up to host the biggest crowd it has ever welcomed for the June 3 match when Real Madrid will take on Juventus at the Millennium Stadium. South Wales Police has been given £177,000 ($230,000) to pilot the facial recognition technology, which will monitor people on pre-determined'watch lists' These watch lists may include dangerous wanted or missing persons. Facial recognition identifies people by analysing the shape of a person's face. Each face has approximately 80 unique nodal points which distinguishes one from another.
