What is the primary function of an access control system?

The primary function of an access control system is to restrict access to authorized users. This is essential for ensuring security within a facility by allowing only individuals who have been granted permission to enter specific areas or access certain information. By implementing various methods of authentication, such as key cards, biometrics, or passwords, access control systems help prevent unauthorized access that could lead to theft, vandalism, or data breaches.

While monitoring employee attendance and providing customer service may be important aspects of a business's operations, they are not the main goal of access control systems. These systems focus specifically on enhancing security by controlling who can enter or exit premises or access critical information systems. Effective management of an inventory is also unrelated to the core purpose of access control systems, which is fundamentally about authorizing and restricting access.
