Is iris scanning usually performed surreptitiously?

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (B)

Iris scanning isn’t usually surreptitious because it relies on direct interaction with a sensor: the person must look at the camera, be positioned at a specific distance, and the system uses infrared illumination to capture a clear iris image. This setup is typically visible at controlled entry points (like security checkpoints or doors with access control), often with signs or instructions, so people are aware they are being scanned. While there can be rare, exceptional cases in experiments or misuse, in everyday practice iris recognition is not performed covertly. Hence the statement is false.
