A Security Checkpoint is a designated area where individuals and their belongings are screened for safety and security purposes. These checkpoints are commonly found in places like airports, government buildings, and large events. The goal is to prevent prohibited items, such as weapons or explosives, from entering secure areas. At a security checkpoint, personnel may use metal detectors, X-ray machines, and manual inspections to examine bags and personal items. Travelers often need to present identification, such as a passport or driver's license, to verify their identity before proceeding. This process helps ensure the safety of everyone in the vicinity.
