How long does it take to approve the validity period of Zhenhai Refining and Chemical Industry Access Permit?

Access cards are generally permanent, but they also depend on the property in your community. If this property does not update the access card, you can always use it.

Access card refers to the cards used in the access control system, such as access card, access card, parking card, membership card, etc. Before issuing access cards to end users, the available areas and user rights are determined by the system administrator. Users swipe their cards to enter the management area. Users without access cards or permissions are not allowed to enter the management area.

There is a chip called RFID in the access card. When the user passes the card reader with a card containing RFID chip, the electromagnetic wave emitted by the card reader will start to read the information in the card, which can not only be read, but also written and modified. Therefore, the chip card is not only a key, but also an electronic identity.
