With appropriate software in PC, user can select this LFD feature so that only live finger's fingerprint will be scanned into PC. Special electronic circuit is built into FS80H to do Live Finger Detection (LFD). The finger is illuminated by 4 infra-red LEDs during scanning and the light intensity is automatically adjusted according to scanning fingerprint's characteristics (wet, dry, blurred, etc) to optimize the quality of the captured fingerprint image. So it is much more reliable and robust compared to any semiconductor type fingerprint sensor. Its finger scanning window is a crown glass with a thickness of 14mm. So it is good for any fingerprint recognition application. It can capture an almost un-distorted raw fingerprint image into PC in 100ms. Futronic FS80H Fingerprint Scanner uses advanced CMOS sensor technology and precise optical system to deliver high quality fingerprint image.
