Which statement about iris recognition is true?

• A. It has high FARs
• B. Iris recognition scans the eye with lasers
• C. Iris recognition technology is expensive
• D. All of the above

Answer: (C)

Iris recognition is expensive because it relies on specialized optical hardware, secure enrollment workflows, and powerful processing to extract and compare iris features. The imaging system uses high-resolution infrared cameras and controlled lighting to capture a clear iris pattern, plus robust algorithms to generate secure templates and protect user data. All of this adds cost and maintenance compared to simpler biometrics. The claim that it has high false accept rates is not accurate; iris recognition is known for its high accuracy and very low false accept rate. It also does not scan with lasers—the imaging is done with infrared illumination, not laser. Because of these factors, the true statement is that iris recognition technology tends to be expensive.
