A Biometric Fingerprint Time Attendance System is an electronic device used to capture a digital image of the fingerprint pattern. The captured image is called a live scan. This live scan is digitally processed to create a biometric template (a collection of extracted features) which is stored and used for matching. These days generally USB Biometric Fingerprint Attendance Machine is available from different manufactures and connects with the PC/Laptop through their USB Port; a basic application with Biometric Fingerprint Machine Driver is required to make it working.

There are different kind of Biometric Fingerprint Attendance Machine are available and these are categorized based on the Saviour Technology its usages, important of them are – Optical Fingerprint machine Ultrasonic Sensors, Thermal Sensors, Capacitive Fingerprint Scanners and swipe fingerprint scanners.
Biometric fingerprint scanner captures the digital image of the fingerprint machine using visible light. Below the touch surface of the biometric fingerprint scanner there is a light-emitting phosphor layer which illuminates the surface of the finger. The light reflected from the finger passes through the phosphor layer to an array of solid state pixels (a charge-coupled device) which captures a visual image of the fingerprint. Optical Biometric Fingerprint Scanners are the commonly used fingerprint scanner for different applications.
