• A. To provide a remote control for CCTV systems
• B. To provide a secure and portable means of accessing restricted areas
• C. To validate the effectiveness of a security system
• D. To store user credentials for easy access

Answer: (B)

The purpose of a "key fob" is to provide a secure and portable means of accessing restricted areas. Key fobs are small electronic devices often used in access control systems. They typically contain a chip that communicates with a reader, allowing authorized individuals to gain entry without needing a traditional key. This enhances security by ensuring that only those with the proper authentication can access specific areas. The convenience and portability of key fobs also make them a practical choice for users, enabling easy access without the hassle of physical keys. Additionally, many key fobs operate on a proximity basis, allowing for quick entry when the fob is in close range of the reader, further streamlining access control processes. This helps organizations maintain security while offering users a user-friendly method to access restricted areas.
