Why do you seldom see the code-scanning charging treasure in the library? One of the main reasons is for safety. In recent years, there have been many incidents such as the fire of Shenzhen subway charging treasure and the explosion of Guangzhou subway charging treasure. Different from shopping malls, subways and other public places, the library is a unit that mainly stores books and belongs to the national first-class key fire prevention unit. There are many paper books and few channels in the library. If there are many people like this on Saturday and Sunday, the improper use of scanning code charging treasure will explode, causing a fire, and the consequences are unimaginable.
Secondly, most people who come to the library come to read paper books, and there is little demand for electronic equipment. Even if you want to bring electronic equipment to study, you will charge it in advance, and there are several sockets in the library. If you need to charge, you can bring your own charger for safe and orderly charging.
