biometric revolution has been a great contribution in modern science. Fingerprint attendance machine is also a part of this revolution. A fingerprint attendance machine analyzes several fingerprint patterns for matching purpose. These patterns include arc pattern, loop pattern and whorl pattern.

Finger punching attendance machine has an electronic device which is called sensor and is used to capture digital reflection of fingerprint prototype and the captured reflection is called live scan. Finger punching attendance machine has various fingerprint sensors. Few of them are optical, ultrasonic, capacitance, passive capacitance etc. Finger punching attendance machine works in two different ways- first it captures the image of the fingers through the sensors and second it matches the image with previously enrolled fingerprint templates. Several software applications are available in the market for finger punching attendance machine.
