There's purpose in using photoplethysmography/photoxytometry (this
gives you oxygenation of the blood plus pressure pulses with a little
DSP on NIR/red LED light) together with papillary pattern matching,
as this would reject forgery with crude replica. Or amputated limbs.
Of course, pure biometrics is cargo cult security.
