What is the single badge system?

• A. The EC compares the badge photo to the bearer; easier to defeat; use supporting techniques.
• B. Uses two badges with two face checks.
• C. No verification occurs.
• D. Verification is performed solely by EAL.

Answer: (A)

A single badge system relies on a single visual check: the entry controller compares the photo on the badge to the person presenting it. Because only one factor is used for verification, this approach is more vulnerable to impersonation, badge sharing, or a badge being presented by someone other than the rightful bearer. To compensate for that weakness, security normally adds supporting techniques—extra checks that occur alongside the badge verification. These might include occasional identity confirmation by staff, watching for tailgating or other suspicious behavior, using time- or location-based controls, and coupling the badge with another method (for example, requiring a PIN or a biometric check on higher-security doors) when needed. In short, the single badge system is defined by the EC performing the photo-to-person match as the primary verification step, with additional safeguards used to bolster security because the single check is comparatively easier to defeat.
