Alipay, a China-based online payment platform by Alibaba Group, has come up with an innovative digital payment system in China. The technology allows customers to make payment by merely flashing a smile that authenticates customers’ identity for the online transaction.  Introduced as a beta version in 2015 by Alibaba’s founder Jack Ma, the service has now been launched by the company’s Ant Financial Affiliate in Hangzhou headquarter, where the technology is being trialed with KFC. It makes use of Face++ functionality from Chinese startup Megvii.
