Which system is described as more secure due to dual badges and color-coded cards?

• A. The exchange badge system.
• B. The single badge system.
• C. The no-badge entry system.
• D. The universal badge system.

Answer: (A)

In security systems, using two badges plus color-coded cards provides layered protection and quick visual verification. The exchange badge system requires presenting two separate badges, creating a form of two-item authentication: you must possess both tokens to gain access, which helps prevent someone from entering if one badge is lost or stolen. The color-coded cards add an immediate, at-a-glance way to distinguish clearance levels, roles, or validity, allowing guards to quickly spot mismatches or expired credentials and respond accordingly. This combination strengthens access control beyond a single token and beyond uniform, generic access. The other options don’t deliver the same level of layered verification. A single badge system relies on only one credential, so compromise of that badge can grant broader access. A no-badge entry system has no token at all and is inherently less secure. A universal badge system suggests broad, perhaps all-access credentials, which defeats the purpose of differentiated access and reduces security effectiveness.
