China fast-food operator pilots face-recognition payments
The "Smile to Pay" system will allow customers at a healthier spin-off of KFC in the eastern city of Hangzhou to keep their wallets in their pockets after ordering on a machine.
Yum China, which operates several major fast-food brands in China including KFC, Pizza Hut and Taco Bell, teamed up with Chinese mobile payments firm Alipay -- started by e-commerce giant Alibaba -- on the technology.
Yum China called the concept a "world's first".
The ordering machine will compare the customer's face with the verified picture on their Alipay account.
China is racing ahead in its use of facial recognition technology.
It has even been installed at Beijing's historic Temple of Heaven to stop people pinching rolls of toilet paper.
Airports and train stations are also jumping on the trend, with China Southern Airlines this year using facial recognition in place of boarding passes for the first time.
And in Qingdao, home to China's most famous lager, 25 suspects were recently arrested after they turned up to a beer festival only to be identified by the technology at entrance gates.
