Competition in the mobile payment market has ignited the technical progress of both Alibaba and WeChat. To quicken the payment process and to improve user experience, the two tech titans came up with the idea of “pay with faces” which frees the user from using phones scanning QR codes to complete orders, instead, it deploys a 3D depth-sensing camera for the facial recognition payment function. Though WeChat is two years behind Alipay in terms of such technical implementation, it is certainly attracting more attention as the acknowledgment of the reality of a cashless society grows ever stronger.
