Which group has the highest rate of unreturned badges at an airport?

• A. Pilots
• B. Construction Workers
• C. Vendors
• D. Visitors

Answer: (B)

Credential lifecycle and access control are being tested here—the idea that managing who has a badge, how long they keep it, and reclaiming it when they’re done is crucial for security. Construction workers tend to have the highest rate of unreturned badges because many individuals work on a site through short-term or varying contracts, often across multiple subcontractors. The sheer turnover, frequent shifts, and the complexity of tracking dozens or hundreds of workers can make reclaiming badges after a project or contract ends easy to overlook. In contrast, visitors are typically checked out at exit, vendors operate under more formal close-out procedures, and pilots’ access is tightly controlled through other means, reducing the chance of unreturned badges. So the transient, high-traffic nature of construction work on a secured airport site drives the highest unreturned badge rate.
