Guangzhou Metro pilots facial recognition at ticket barriers
South China city subway adopts facial recognition — Xinhua — “Instead of using tickets or swiping their smartphones, passengers can smile at a screen to unlock the electric gates in about half a second after completing a real-name registration on Guangzhou Metro’s official mini-program on WeChat, China’s popular social media platform, or on the ‘Guangzhou Metro’ mobile app. The fee will be deducted from the payment methods that subway riders previously register and validate through their mobile phones.”
