Which method identifies users based on hand shape and size?

• A. Hand Geometry
• B. Virtual Token
• C. Accounting
• D. Text Message Authentication

Answer: (A)

Hand geometry is a biometric method that identifies users by measuring the size and shape of the hand and fingers—lengths, widths, and contours of the palm and digits. This approach relies on physical attributes, making it suitable for verifying a person based on how their hand is shaped and sized. The other options don’t match this approach: a virtual token is a possession-based method that generates codes, not a measurement of the body; accounting is about tracking activities and is not an authentication method; text message authentication uses codes sent to a phone, which is another factor rather than a biometric measurement.
