(2017 Sep) Alipay Launches ‘Smile to Pay’ for Commercial Use in China

Alipay has launched its new facial-recognition payments technology for commercial use, Ant Financial Services Group said Friday.
“Smile to Pay,” the first service of its type, debuted at a KFC’s new, healthy-food concept restaurant, called KPRO, in Hangzhou. With it, Alipay users can authenticate their payments through a combination of facial scanning and inputting their mobile phone numbers. That means they won’t need to break out their wallets—or even smartphones—anymore.

Ant Financial said the Smile to Pay technology has reached a level of accuracy and security that should put Alipay users at ease. The multistep process of one to two seconds of facial scanning uses a 3D camera and a “live-ness detection algorithm” to guarantee a user’s identity. For example, the algorithm can detect shadows and other features that can only come from living beings, thereby blocking photos or video that might be used by someone trying to hijack a person’s Alipay account. The addition of the phone-number check “further ensures the security of transactions,” Ant Financial said.
