According to feedback from friends who have been to Guangzhou, mobile phones in other places scan codes vertically. Guangzhou was scanned by a mobile phone lying with its screen facing upwards and stuffed into a code scanner. So unfamiliar people may really not be able to operate. In fact, things like not paying by mobile phone are very common in life. Just like the first time I bought a subway ticket with an automatic ticket vending machine, I fiddled with it for a long time, and then I hit it by mistake.
So now you don't have to scan the QR code to pay. People who scan their mouths with the payment code should put a suggestion process next to them, preferably in the form of pictures, to provide convenience for more elderly people. I don't think that man can't pay by mobile phone, but he doesn't know the alternative mobile phone payment in Guangzhou. If it is my first time to use this method, maybe he will make a phone call like him and put it in the change box by mistake.
Although the current mobile payment has indeed brought endless convenience to our lives, so that each of us can do almost everything with a mobile phone when we go out, the jokes made through Alipay are endless, which shows that it still needs to be improved. I hope my father Ma Yun will make persistent efforts to make our life more convenient.
