Yum China Holdings is testing self-serve kiosks with facial recognition at a store called KPRO in Hangzhou, according to Fox News. Yum China Holdings spun off from its former parent company, Yum Brands Inc., a year ago.

Customers go to a self-serve kiosk to choose items on a video screen, then pay by looking at a camera, provided they've enabled facial-recognition on their Alipay app. For security, they must also enter their phone number.

Customers place orders via smartphone, using QR codes printed on tables, or through the facial recognition system that matches their images to their Alipay wallets.
