Who needs tickets when you have a face? From today, the ticketed tourist town of Wuzhen in China is using face-recognition technology to identify people staying in its hotels and to act as their entry pass through the gates of the attraction. The system, which is expected to process 5000 visitors a day, has been created by web giant Baidu – often referred to as the “Chinese Google”.

Wuzhen is a historic town that has been turned into a tourist attraction with museums, tours and traditional crafts. When people check in to hotels in the tourist area, they will now have their pictures taken and uploaded to a central database. If they leave and re-enter the town, the face-recognition software will check that they are actually a guest of a hotel there before allowing them back in. FULL REPORT
