FAQ on the Biometrics attendance system.
1. Which is the recommended finger to be used for a fingerprint scanner?
You can use any of the ten fingers for verification. The index and thumb are much easier for the scanner to capture rather than other fingers.
2. Does this fingerprint device secure?
It is highly secure for you, and it enhances your privacy by providing encryption and biometrics functionality. In this technology, fingerprints cannot be duplicated, lent, or stolen.
3. Can fingerprint images be duplicated?
No. The fingerprint image is not stored; it uses the algorithm concept before the mathematical data is stored as uniquely yours. The fingerprint obtained from other sources will not be recognized as a life finger is needed for verification.
FAQ on the Face Recognition Terminal.
1. How accurate of face Recognition?
Facial Recognition systems can have near-perfect accuracy. Verification algorithms used to match subjects to clear reference images can achieve accuracy scores as high as 99.97%. This is comparable to the best results of iris scanners. This kind of face verification has become so reliable.
2.What is the criterion for facial recognition?
Face recognition software employs computer algorithms to identify unique features on a person’s face. These data, such as eye range, are transformed into a mathematical representation and contrasted to data from other faces in a face recognition database.
