Facial recognition might soon become the norm for payments, with a KFC outlet in Hangzhou, China, receiving commercial payments using the mechanism. Alibaba's Ant Financial affiliate launched the'smile to pay' service at the outlet as part of the company's proposed system of cash-less retail stores, in which it will integrate offline and online retail. All that a customer needs to do is smile at the interface and the payment will be made. The system does not require a smartphone based authentication; all that is needed is to sign up for the Alipay app and enable facial recognition. The point of sale, in this case the KFC outlet, will be equipped with a 3D camera, which will verify a customer's identity by scanning his/her face.
