Why is there no card reader in front of Yongda elevator in our building?

It is estimated that the property is convenient to manage and the owners are convenient to go upstairs and downstairs. After all, elevators are also public facilities. Sometimes they don't come up for a long time in an emergency, or there are too many foreigners in the elevator, so they can only install a card reader, which is also convenient for the owners to go upstairs or downstairs as soon as possible in an emergency. It is also convenient for owners to confirm whether they are acquaintances when they meet foreigners, and it also ensures the safety of owners and the efficiency of elevators!
