Biometric devices are hardware systems used to capture, process, and verify unique biological traits (biometrics) for identity authentication or access control. These traits are unique to individuals, making biometric security highly reliable.
Types of Biometric
- Fingerprint: Captures unique patterns of ridges and valleys on a person’s finger.
- Face Recognition: Analyzes the unique features of the face, such as the distance between eyes, nose, and mouth.
- Iris Recognition: Scans the unique patterns in the colored part of the eye.
- Retina Scan: Captures the unique patterns of blood vessels in the retina.
- Voice Recognition: Analyzes the unique vocal patterns of a person.
- Palm Vein Recognition: Scans the vein patterns in the palm of the hand.
- DNA: Involves genetic information, though not typically used in real-time authentication.
Applications:
Attendance, Security and Access Control
