Which of the following offers greater accuracy then the others?
A.
Facial recognition
B.
Iris scanning
C.
Finger scanning
D.
Voice recognition

Iris scanning offers greater accuracy than finger scanning, voice or facial
recognition, hand geometry or keystroke analysis. It is safer and less invasive than
retinal scanning, an important legal consideration [Nuger]. Any company thinking of
