You can pay at a restaurant by smiling at a camera
As easy as it is to make purchases in the era of tap-to-pay services, it's about to get easier still. Alipay (which handles purchases for Chinese shopping giant Alibaba) has launched what it says is the first payment system that uses facial recognition to complete the sale.
