Scanning code to order food will enter our dining habits, and this information is easily known by other stores, so that we often receive some spam messages, and it is easy for us to brush these videos when we brush them, thus stimulating our consumption in other stores.

First of all, our information may be leaked. If the person who scans the code to order food knows that he needs to log in before ordering food, he may use WeChat or Alipay to order food. In these two softwares, our identity information is completely transparent. Because our bank card and our ID card are registered in these two softwares, if our information is leaked because of scanning code payment, the consequences will be very terrible. Most of these software for scanning codes and ordering food are made by some small companies. They can't guarantee the security of this application, nor can they guarantee that the customer's information will not be leaked. Therefore, the most serious security risk of scanning code to order food is that it may expose our identity information and affect our property security.

Second, we will record our eating habits. Now big data is also terrible. When we play mobile phones, we will find that after we like a short video, there will be countless similar short videos. This is that big data will identify our personal hobbies and then recommend them to us according to our hobbies. Something we'll like. The same is true for ordering software. They will remember our eating habits and the food we usually like to eat. After these are known by other catering companies, they may often recommend us all kinds of foods we like. Some people can't help wanting to taste these foods when they see them. After our data is known to others, others may also use our weaknesses to deceive us, so there are some loopholes in scanning the code to order food.

Third, our payment password is also easy to leak. In the process of scanning the code to order food, we often enter our own payment password, because only after these orders are paid successfully can the waiter serve us food. The hotel is full of people coming and going. In the process of paying the password, we can't guarantee that people around us won't peek. Once our payment password is leaked, our property will be very unsafe, because now everyone will only bring a mobile phone when they go out, and face recognition is rarely returned during the payment process. We can directly enter the password to pay for our money. If we are too cautious when paying the password outside, people around us will think that we are too wary of others, so there are still many hidden dangers in scanning the code to order food.
