Why is property management so difficult to do?

Owners are obliged to remind them to carry their key cards with them. However, in the actual property management, some owners still have the habit of forgetting or not taking it. Therefore, it is necessary to put a roster of park owners at the entrance and exit gate, and verify the identity of owners or tourists without key cards before deciding whether to release them. This is the responsibility of the entrance and exit gate, and it is also the normal management of the property.
