KFC China is using facial recognition tech to serve customers - but are they buying it?

Beijing KFC is pioneering technology to try to predict and remember people's fast food choices but there's a trade off between convenience and privacy

Walking into the KFC restaurant in Beijing's financial district, you'd be forgiven for thinking it was a fried chicken outlet like any other. It's only if you head right to the back corner of the shop that you realise you're actually in China's first smart restaurant.

KFC has teamed up with Baidu - the search engine company often referred to as "China's Google" - to develop facial-recognition technology that can be used to predict customer's orders.
