What must be provided to visitors to distinguish them from onsite personnel and indicate expiration?

• A. Visitors are identified and given a badge or other identification that expires and visibly distinguishes them from onsite personnel.
• B. Visitors receive a permanent badge that never expires.
• C. Visitors are only required to sign in but receive no identification.
• D. Visitors carry a personal ID that can be used for multiple visits.

Answer: (A)

The main idea is that physical access needs clear, time-limited identification to distinguish visitors from staff and to prove who is allowed in and for how long. Giving visitors a badge that expires and looks different from onsite personnel provides two crucial controls: it marks them as temporary and non-employee, and the expiration date enforces a defined time window for access. This makes it easy for security staff to verify legitimacy at a glance, helps prevent someone from using an old or revoked credential, and supports proper monitoring and escorting if needed. Other approaches fall short because a permanent badge never signals temporary access, so it can be reused or reused inappropriately; signing in without any identification offers no way to verify identity or eligibility; and using a personal ID that can be used for multiple visits can blur the line between visitors and employees and may not provide a reliable, time-bound credential.
