Which type of lock is typically considered a biometric lock?

• A. Combination lock
• B. Fingerprint scanner
• C. Padlock
• D. Digital keypad lock

Answer: (B)

The correct choice, a fingerprint scanner, is classified as a biometric lock because it utilizes unique biological characteristics to grant access. Biometric locks assess physical traits such as fingerprints, facial recognition, or iris patterns, making them highly secure and difficult to replicate. In contrast, combination locks, padlocks, and digital keypad locks do not rely on biological traits for authorization. Combination locks use a sequence of numbers or symbols, while padlocks can be opened with a key or a combination. Digital keypad locks require a user to input a specific code, but all these options depend on knowledge or possession rather than a physical biological attribute. This reliance on unique, personal physical characteristics is what distinguishes biometric locks, like fingerprint scanners, from other types of locks.
