Yum China Holdings Inc, operator of 5,300 KFC restaurants across China, introduced its first facial-recognition ordering kiosks in a concept store named KPRO in Hangzhou featuring low-calorie menus.

The tie-up with Alipay, the country's largest mobile wallet, in commercializing such technologies underscores the ongoing digitalization push of the fast-food chain to leverage two trends: resonating with tech-savvy diners and jumping on the healthy-eating bandwagon.
