A security badge is an identification card that grants access to restricted areas within a building or facility. It typically includes the holder's name, photo, and sometimes a unique identification number. Security badges are commonly used in workplaces, schools, and government buildings to enhance safety and control entry. These badges often come with additional features, such as magnetic strips or RFID technology, which allow for electronic access control. This helps ensure that only authorized personnel can enter sensitive areas, thereby protecting valuable assets and maintaining a secure environment.
