Which biometric method measures the shape and size of the hand for verification?

• A. Hand geometry
• B. Facial recognition
• C. Retina scanning
• D. Finger printing

Answer: (A)

Hand geometry is the biometric method that measures the shape and size of the hand for verification. It captures physical dimensions such as hand width, finger length, and the distances between key points, usually with a scanner or plate. This focus on hand dimensions distinguishes it from other methods: facial recognition uses facial features, retina scanning looks at retinal blood vessel patterns, and fingerprinting analyzes fingerprint ridge patterns. The question targets the hand’s physical dimensions, making hand geometry the correct choice.
