What information must be contained on a security badge?

The correct response highlights that a security badge must contain both the agency name and the designation "Guard" or "Security." This information is essential because it clearly identifies the individual as a representative of a licensed agency and outlines their role. The inclusion of the agency name ensures accountability and allows the public to ascertain which organization the security personnel are associated with. The designation "Guard" or "Security" further clarifies the individual's position, allowing people to easily recognize their authority and function within the scope of their duties.

The necessity for the badge to exhibit these details is part of standardized practices in the security industry, aimed at ensuring professionalism and transparency for the public. The options that suggest only one element, such as just the last name, or only the agency name, do not provide sufficient information to identify the guard’s role or the agency they represent, thereby lacking the clarity and authority needed for effective security operations.
