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 various tools, such as metal detectors and X-ray machines, to inspect bags and personal items. Travelers often need to present identification, like a passport or driver's license, and may be required to remove shoes or belts for thorough screening.
