Which of the following is an example of credentialing and biometrics within airport security systems?

• A. Weather radar
• B. Luggage conveyor system
• C. Credentialing and biometrics (identity management)
• D. Food service

Answer: (C)

Verifying who someone is and controlling access relies on credentialing and biometrics. Credentialing covers the issuance and management of identity credentials like boarding passes or security badges, while biometrics adds a verification step by comparing unique physical traits (such as fingerprints or facial features) to confirm the person’s identity. Together, identity management and biometric checks enable secure boarding, restricted-area access, and traveler verification at checkpoints. The other items serve operational roles—weather monitoring, baggage handling, or food service—and do not involve confirming a person’s identity or controlling access.
