"It works just as one might expect—diners approach a virtual menu, select the item they want to purchase, and then choose “facial scan” as a payment option. Users must input their phone numbers as an extra layer of verification, but the technology still works even if one’s phone is turned off, an Ant Financial spokesperson tells Quartz.
A promotional video shows a young female customer scanning her face while donning a wig and appearing with friends, to tout that the technology can recognize an individual even if they are disguised or in a group.
Alibaba’s Jack Ma first introduced the technology at a tech conference in Germany in 2015, dubbing it “smile to pay.” While Ant Financial has since let users login to its Alipay mobile payments app using facial scan, the KFC partnership marks the first time it has been rolled out for commerce. An Ant Financial spokesperson tells Quartz that it intends to roll out the scanning at more locations later."
