The advantages of upgrading access control card to CPU cards

The access control card system issues the card ID to the access control controller, and compares the card ID with the information stored in the controller when swiping the card to confirm whether it has access permission. This comparison has the highest efficiency, but it requires the system management to issue data to each access control controller. If there is a network failure or a new controller needs to be replaced, data needs to be reissued, which can easily lead to inconsistent results and is difficult to manage. If a user creates multiple access Cards for multiple application systems in the later stage, the original access Cards may be difficult to use due to mismatched system functions.

If users want to upgrade their current access card system, they can consider a new application mode. Firstly, integrate the system software to minimize the complexity of operator operations. Secondly, upgrade the card carrier to a CPU card, fully utilizing its advantages in storage capacity and encryption features. Upgrade the system as necessary, set access permission codes for each access control controller, and set the codes according to the agreed rules. Due to the increased storage space of the CPU card and the adoption of directory and file management for data reading and writing, a separate storage space can be opened for the access card system, and the access permission codes of each access card can be directly written into the card. In this way, each card has its own access permission, and the CPU card reader cooperates with the access control controller during entry and exit. The card can be directly authenticated through the internal authentication program of the controller. This eliminates the need to send data to the access control controller and fully utilizes the storage capacity advantage of the CPU card. The above upgrade methods for the access control system have to some extent improved the security and ease of operation of the system. Before practical application, extensive testing is needed to evaluate the efficiency and stability of this access control authentication method. Authorize each access control controller in the initial stage, which is essentially writing permission codes to the controller. It should be noted that the controller needs to have a built-in authentication program to control the card authentication process. Authorization for the controller only needs to be done once during the initialization phase.
