Scanning code to order food is optional, but it should not be the only choice. Whether to scan the code to order food should be decided by the customer himself. Forcibly asking customers to authorize location, photo album, address book and other information, paying attention to the official account or registered member of the merchant WeChat, and collecting personal biometric information beyond the scope has violated consumers' rights such as fair trading rights and independent choice, and even deviated from the relevant provisions of the Cyber Security Law on the protection of personal information.

At the same time, once the merchants collect the personal biological information of consumers, whether there are corresponding technical means and hardware facilities to ensure the safety of personal information, whether they will resell the personal information of consumers for profit, and whether they will send advertising information to consumers at will without the consent of consumers, which will bring unnecessary troubles to consumers, is probably a question in the minds of many consumers.

What is more noteworthy is that the "one size fits all" behavior of scanning code to order food ignores the dining experience of some elderly people. Even if it is more efficient and convenient to order food by scanning the code, some elderly people have a low degree of use of smart phones and the Internet because of their weak awareness of the Internet and limited economic conditions, and it is more difficult for them to adapt to an increasingly digital and intelligent life.

Scanning code "across the board" not only affects the dining experience of elderly customers, but also directly or indirectly affects the income of businesses.

From the point of view of service and convenience for consumers, merchants should make scanning code to order food no longer the only choice, and win customers' favor with sincere service instead of using commercial bullying to achieve their commercial goals.
