The hotel ID card registration system shows that please contact others. What is the reason?

If the registration system fails, it may not be displayed. As long as the normally used ID card is not illegal, it can generally be displayed. It is recommended to try logging in several times.

Hotels belong to public places. No matter where you travel, you need to find a hotel or guesthouse as a foothold. Because it is a public place, it accepts tourists from all over the world. Hotels, guesthouses and other places are short-lived, and most people stay in 1-2 nights and leave.
