An access control system is primarily used to restrict entry to certain areas based on permissions. This means it serves as a security measure that allows only authorized individuals to enter specific locations or access particular resources. These systems typically involve mechanisms such as key cards, biometric scans, or password-protected entry points, ensuring that only those who have been granted access can enter secured areas. This is crucial in maintaining the safety and security of sensitive locations, protecting assets, and ensuring that personnel comply with established security protocols.

The other options revolve around different workplace functions that do not directly relate to the core purpose of an access control system. While effective communication, grievance handling, and monitoring productivity are important in any organization, they do not pertain to the system designed specifically for regulating physical access based on predetermined permissions.
