Alibaba's Ant Financial affiliate launched its facial recognition payment system at a fast food restaurant in Hangzhou City, China on Friday.

The facial-recognition payment system, named "Smile to Pay", opened to the public in a new KPRO store, a sub-brand of KFC China.

It enables consumers to pay without using any cash, bank card or mobile devices. A consumer who has an Alipay account can link their Alipay account with their face by staring at a Simle to Pay's 3D webcam, which will take a picture and scan the consumer's facial information.
