Which statement about fingerprint scanning is true?

• A. Fingerprint scanners are very expensive
• B. Fingerprint recognition is easily deceived
• C. Fingerprint recognition is rarely used
• D. All of the above

Answer: (C)

Fingerprint scanning is a widely used and cost-effective form of biometric authentication. Modern fingerprint sensors are inexpensive to manufacture and are embedded in many devices and access systems, from smartphones to laptops and door controls. While there are spoofing techniques, contemporary systems include anti-spoofing measures and liveness checks to make deception much harder, so fingerprint recognition isn’t considered easily deceived in everyday use. Additionally, fingerprint authentication is far from rare; it’s one of the most common biometric methods due to its quick speed, low user friction, and decent accuracy. Given that, the statement claiming fingerprint recognition is rarely used would not align with real-world adoption, and the idea that it is very expensive is typically inaccurate for current sensors. The overall takeaway is that fingerprint scanning is a common, affordable, and reasonably secure authentication option when properly implemented.
