Diners at a KFC store in the eastern Chinese city of Hangzhou will have a new way to pay for their meal. Just smile. Customers will be able to use a “Smile to Pay” facial recognition system at the tech-heavy, health-focused concept store, part of a drive by Yum China to lure a younger generation of consumers. Diners can pay by scanning their faces at an ordering kiosk and entering a phone number - which is meant to guard against people cheating the system.The store’s menu offers seasonal produce, made-to-order salads and paninis. The chicken on the menu is “roasted”, while drinks include freshly squeezed juices, gourmet coffees and craft beer. KFC have also launched a limited edition smartphone to celebrate 30 years since it first opened in China.
