In normal use, the elevator controller in Tengzhou Central City of Zaozhuang will control the elevator, and only the cardholder can use the elevator at this time. When the cardholder's card is a single-layer authority card, the elevator will directly register the corresponding authority layer after the user swipes the card. When the cardholder's card is a multi-layer authority card, the user can choose to press the floor button with authority on the elevator control panel after swiping the card, and the button without authority is still invalid.

Elevator cards are divided into square cards, key chain cards and glue drop cards. A square card is as big as a business card. They left the factory as white cards. In actual use, they will be printed on both sides. Square cards are generally used as employee cards in companies. The key chain is stuck in a drop shape, which is convenient to carry on the key ring for community users to use. Drip cards have smooth appearance and different shapes, which are more beautiful after printing various patterns.
