Can I cancel the elevator card if I lose it?

If the elevator card is lost, it can be invalidated. If the elevator card is lost, you can report the loss to the property, cancel the lost elevator card, and then issue a new elevator card.

Because as long as we pay the property fee and elevator fee, he must come to us, which is a responsibility. As long as you lose it, you can go to him, but you have to charge a certain fee, that is, the cost of your elevator card.

Elevator card principle

The elevator card is actually an access card. A special access control system, the so-called ladder control system, is installed in the elevator. It needs to swipe the elevator card, the elevator up and down keys will be awakened, and the designated floor key will be awakened.

There are generally four wires, two power wires and two signal wires in the elevator. The card reader is just a switch. Just disconnect one signal line of the button and connect the control signal line of the card reader into the disconnected signal line. When someone swipes the card, it is equivalent to switching on the button signal line and realizing the floor selection. When no one swipes the card, the button signal line is disconnected and the floor cannot be selected.
