Is the elevator fee charged by the elevator card?

Generally, there is no charge, and invalid charges are unreasonable.

There are two main ways to charge the elevator card: by time and by floor. Within the effective number of times, the owner will normally swipe his card to take the elevator, and the number of times in the card will be reduced accordingly. The elevator special card reader uses digital tube to display the card swiping, and displays the remaining times after each card swiping. When the number of times in the card is close to zero, the owner needs to recharge it at the property management center in time, otherwise the elevator special card will be invalid when swiping the card, and the elevator button will not respond. When the owner pays the fee and swipes the card again, the elevator button on the owner's floor will automatically light up and go straight to the owner's floor for normal use. The elevator button on other floors is invalid, and there is no card or unpaid owner.
