WHY FOUR FINGERS INSTEAD OF ONE? WHY TOUCHLESS OPERATION?
AVOID IDENTITY THEFT
Touchless operation rules out capturing latent fingerprints on touch-based sensors
Higher security level
Fingerprints of four fingers require substantially more spoofing effort than just one finger
No more hygienic issues
Touchless operation avoids collecting and growing bacteria on the sensor
Touchless capturing copes much better with wet or dry fingers
