Aviation and Airport Security Practice Test.

The term "access badge" in airport security refers to an identification credential that grants individuals entry to restricted areas within the airport. These badges are essential for maintaining security, as they ensure that only authorized personnel can enter sensitive zones such as runways, baggage handling areas, and other high-security locations.

Access badges typically include features such as the individual's name, photo, and expiration date, along with security elements to prevent counterfeiting. They serve to mitigate security risks by verifying the identity of those who require access to secure areas, thus helping to ensure a safe airport environment.

The other options describe different aspects of airport operations. A boarding ticket is for passengers to gain access to their flights, while duty-free shopping passes facilitate purchases of tax-exempt goods, and vouchers are linked to airport lounge access for travelers. None of these options relate to the security functions that access badges fulfill in controlling entry to restricted areas.
