With only 127 people being tested and a false positive rate of 0.7% I'd be hard pressed to see this as a viable system in its current form.

It's certainly less invasive but you have to ask how effective it can possibly be when it's known about. It's a lot harder to fake your fingerprints and retina than to walk at a different speed.

If you were a highly funded individual you could also quite easily acquire one of these systems and practice to fool it.

I don't see how this could be used as a effective security system but maybe someone could enlighten me.
