Explanation
Tailgating (also called piggybacking) occurs when an unauthorized person follows an authorized person through a secured entry point without independently authenticating. Turnstiles are specifically engineered to enforce one-person-at-a-time passage, physically preventing a second person from passing simultaneously. Barriers and fences control perimeter access but do not enforce single-entry at a doorway. Locks secure the door but do not prevent someone from slipping through behind an authorized user. Turnstiles directly counter the mechanics of tailgating.
