A biometric machine is a device that identifies or verifies a person based on unique biological traits instead of passwords or ID cards.
Common types of biometric machines
- Fingerprint scanner – most common; used in attendance systems and phones
- Facial recognition system – scans and matches facial features
- Iris scanner – analyzes patterns in the eye
- Hand geometry – measures hand shape and size
- Voice recognition – identifies speech patterns
How it works
- The machine captures your biometric data (e.g., fingerprint).
- It converts it into a digital template.
- When you use it again, it compares your input with stored data.
- If it matches, access is granted.
