What characteristics must visitor badges have?

• A. Permanent badges with no expiry
• B. Badges that expire and clearly distinguish visitors from onsite personnel
• C. Badges identical to onsite personnel
• D. No badges required for visitors

Answer: (B)

Controlling physical access hinges on knowing who is in the facility and for how long. Visitor badges should be time-bound and clearly distinguish visitors from onsite personnel so security can enforce access rules and quickly identify anyone who should not be in restricted areas. An expiry helps revoke access when the visit ends or credentials are compromised, and clear labeling prevents confusion or impersonation with staff. Permanent badges with no expiry or badges that look identical to employees undermine accountability, and not using badges at all eliminates the ability to monitor or manage access. Therefore, badges that expire and clearly distinguish visitors from onsite personnel are the proper practice.
