Japanese ticket seller Pia and J League, Japan's professional soccer league, are planning to work together on a facial recognition system that automatically cross-checks customers' faces with registered photos.The plan, which is designed to enhance security while improving waiting times, will be tested on 600 to 700 people in the final game of the Levain Cup soccer tournament, which is being held Oct. 15 at Saitama Stadium, reports the Nikkei Asian Review.The newspaper notes that the system uses Canon cameras and face recognition technology from NEC.But checking the face of each customer against registered photos is time consuming, often resulting in long lines at the gate.Last month, concert organisers in Japan started using face recognition to ensure that tickets aren't resold on for profits.The managers of pop group Momoiro Clover Z have been using the technology at venues such as Seibu Prince Dome in Saitama Prefecture, reported the Japan Times.The system is only available for members of the group's fan club. Members must add their photo beforehand to a membership card equipped with an integrated circuit.After paying for a ticket, they need only present their card to get into the venue.
