Ding Sheng elevator credit card system can call the elevator without a credit card.

When the owner buys a house, the salesperson will inform in advance that the elevators in the community are equipped with ladder controls, and only by swiping the card can they reach their own floors.

When the owner comes to pick up the key, the property will provide each family with three cards as standard, which can be used to enter and leave the community gate, unit door and take the elevator at the same time. If the owner later feels that the card is not enough, he can also spend 50 yuan to reissue one.
