What does the term “fob” refer to in electronic access control?

The term “fob” in electronic access control typically refers to a small device that communicates via RFID (Radio Frequency Identification). These devices are commonly used for access control systems, allowing users to unlock doors or gain entry to secured areas simply by bringing the fob into proximity with a designated reader. This wireless communication enables a quick and user-friendly method of access while often reducing the need for physical keys.

The function of a fob is crucial in modern security systems as it integrates with the electronic locking mechanisms and helps streamline the process of authentication. The small size of these devices makes them easily portable, often featuring keychain attachments for convenience.

In contrast, the other options pertain to different aspects of electronic access control systems. For instance, logging access events involves tracking who accessed a location and when, which is not a function of a fob itself. A security protocol generally refers to the rules and procedures governing system security rather than a physical device. Lastly, a server for managing access is a backend component that handles user accounts and permissions rather than being a user-interface device like a fob.
