How Fingerprint Attendance System Works! The term Biometrics combine of two words Bio and Metrics comes from Greek. Bio=life and Metrics=measure. This has been widely used for a personal identification and security. Now day’s biometric time attendance system is becoming to manage attendance system. Fingerprint attendance system works quite efficiently and stops buddy punching.
The biometric fingerprint machine scanner system works efficiently for identification process a biometric physiological finger Scanner works on 2 basic principles.
- Takes an image of a finger
- Finger scanner save specific characteristics of every finger & saved as the form of bio-metric encrypt key
- No one can change the algorithm which is impossible to duplicate fingerprints
- Bio-metric attendance system determines whether the pattern of ridges and valleys in this image matches the pattern of ridges and valleys in pre-scanned images.
- Fingerprint machine scanner is operational and you can easily manage employee’s attendance
- There are two types of biometrics “Physiological” and “Behavior”. For biometric attendance system works physiological biometric technique is used.
Physiological
Physiological bio-metric mean human characteristics, i.e. the shape and composition of the body. This is mostly done by face, fingerprints, hand geometry, retina, iris, signature, vein and voice.
- Face
Physiological face verification used for identification of a person with its facial characteristics and pattern.
- Fingerprints
Finger print technique is another physiological biometric to measure. As every human being fingerprints are different and unique from each other it’s differentiated. So we can use this technique for biometric attendance system works. The accuracy rate of finger print machine scanning is high.
- Hand Geometry
This is done by measuring the length of fingers, shape of the hands & palm geometry of a person.
- Vein
The back side of the hand or wrist is checked to identify authorized person only.
