Scanning the code to stay in the hotel "accepted" makes people think. What's going on here?

Mobile phones are becoming more and more popular, and now you only need one mobile phone to solve everything. A few years ago, many people didn't think that a mobile phone could bring you unimpeded. However, the widespread use of mobile phones also brings many potential dangers, which are inevitable when people go out and stay in hotels. And scanning the code to stay in the hotel has gradually become a daily routine. Some people were "joined" because they scanned the code and checked into the hotel, which made many people feel scared. What's going on here?

Recently, some netizens reported that their mobile phones received messages from various members every day, but after thinking about it, they found that they did not apply for these members, which made them very confused. So they thought about it for a long time and found that when they stayed at the hotel, they were asked to scan the code on WeChat. After scanning the code, all kinds of information about the customer will be understood by the other party, such as ID card, birthday and home address.

It is indeed a very immoral thing for the hotel to sell this information to other businesses immediately without the customer's knowledge. Nowadays, code scanning check-in and code scanning payment are becoming more and more common, and many people see the convenience but don't see the potential danger.

The hotel will also use mobile phone customer information as a resource, collect customer information data, and more importantly, tap customer background and conduct precise marketing. These are things that customers can't imagine. If you think about it carefully, it will really make people feel very frightened. All my information is held by others, but I have no idea at all, and I am in a passive state. After many consumers have reflected this problem, law enforcement departments have also taken corresponding measures, hoping that there will be fewer and fewer incidents of scanning code to stay as a member.
