Revisiting Facial-Recognition Payment: Old Problems Still Lingering

China is a world leader in adopting innovative payment methods. Most Chinese today use their mobile phones to make payments and many people don't carry a physical wallet. Now facial-recognition payment (FRP, 刷脸支付) is gaining traction in China as well. To use FRP, users must first register their face and upload bank-card information to a mobile app. Then, they can complete payments by simply glancing at cameras positioned at the checkout in stores. FRP has become a popular payment method, used mostly in convenience stores, vending machines, and supermarkets.
