Custom Biometrics We create a Biometric Solution for your problem. If the image is roughly acceptable, another algorithm tests the level of biometric thumb, typically by counting the number of scanner and making sure there are alternate light and dark areas as you'd expect to find in a decent fingerprint image. Your fingerprints are like unique keys you carry everywhere.
