Using static QR codes for payments is a very outdated, foolish, and irresponsible method. The payment scan code must have the ability to expire and auto-update, meaning that the QR code needs to be dynamic to withstand financial hacker attacks. For example: Apple Pay can also use QR codes for payments; however, the medium must be a computer screen; refreshing every minute to prevent theft. An even more advanced "QR code" prohibits screenshots; once a screenshot action is detected, the QR code automatically turns white. For instance, the QR code used for logging into a Nintendo account. I don't know if our WeChat and Alibaba don't understand technology or if they are just out of their minds. They actually printed a static QR code directly on paper. What’s the difference between this and an Indian person wiping their butt with their hand after using the toilet? This technology, which leaves financial institutions around the world speechless, is actually being touted by us Chinese as one of the new four great inventions. 😅😅😅
