How should I place my fingerprint on the scanner?
Published: 2012.04.15

Correct method:


 
Place the center of the finger on the center of scanner window.

Wrong method:


 
Too less valid area Too left Too right Defluxion Too down

1. It is better for each user to register two finger prints in case of one finger can not work.
2. Place finger flatly and the center of the finger is on the center of scanner window and press a little hard on scanner so it can scan as large finger area as possible to extract enough minutia.
3. Keep the angle and direction of finger the same each time placing on scanner.
4. If your finger has sweat or water, please make it dry first and then register.
5. If your finger is too dry, make it a little wet or touch the forehead to increase oily of the finger, press a little hard on scanner. The dry finger can cause the finger image not clear.
6. Avoiding the callus, peeling or injury of the finger to ensure the register and identification successful.
7. You’d better register the thumb first, and then index finger or middle finger to increase the precision.
