Does the mall security have the right to check the customer's health code? Is it only the police who have the right?

The security guards here are not only security guards, but also epidemic prevention and control personnel. Therefore, epidemic prevention and control personnel have the right to check the health code.

Now almost every shopping mall or unit needs to check the health code. If it is to let the police check the health code, it is definitely not realistic. There are not so many policemen.
