Application of nfc technology in access control management

In recent years, with the continuous development of intelligent technology, more and more devices have begun to apply NFC technology, including Access Control systems. NFC technology can realize contactless communication. Its advantages are high security, convenient use and simple operation. Therefore, it is increasingly used in access control systems.

In the traditional access control system, users need to carry an access control card or enter a password to pass the access control. However, there are some problems in this method, such as the access control card is easily lost and the password is easily stolen. The access control system using NFC technology allows users to easily pass the access control only by carrying a smartphone.

The application of NFC technology in access control can be divided into two ways: one is to use NFC Tags as the access control identification method, and the other is to use the NFC chip in the smartphone to realize access control identification. Among them, it is more convenient to use the NFC chip in a smartphone to achieve access control recognition, because most people carry their mobile phones with them.

Let's take Shenzhen Nanshan Smart Park as an example to introduce the application of NFC technology in access control systems. Nanshan Smart Park uses NFC tags as the access control identification method. Each employee has an employee card with an access control keychain. When an employee needs to pass through the access control, he only needs to bring the employee card close to the card reader at the access control, and the access control system will automatically read the information in the employee card to determine whether the employee has the authority to pass through the access control. This method can effectively prevent employees from losing their access cards.

In addition, Nanshan Smart Park also applies NFC technology to the visitor management system. Visitors need to make a reservation through the visitor system before entering the park. After a successful reservation, they will receive a text message containing NFC tag information. When a visitor arrives at the access control area, he only needs to bring his mobile phone close to the card reader, and the access control system will automatically read the NFC tag information in the text message to determine whether the visitor has permission to enter the park. This method can easily manage visitors in the park and also improve the security of access control.

The application of NFC technology in access control systems can effectively improve the security of access control and reduce the occurrence of problems such as lost access control cards and password leaks. With the popularity of smartphones, it will be more convenient to use the NFC chip in the smartphone to achieve access control identification.
