Why should I scan the health code when staying in a hotel?

It is what we usually call health code and travel code.

After the outbreak, every guest who needs to stay in the hotel must go through procedures such as temperature measurement, disinfection and code scanning before staying. It is not only necessary to provide the personal health code "green code", but also to check the personal action track, that is, the travel code, to ensure that people who are not in the middle and high risk areas can stay in the hotel, which is also to ensure the safety of individuals and others.
