Fingerprint scan doesn't work for me

[Robo]

BTW... A fingerprint is a 3D image. If prints had no depth, well... there would be no prints.

No more than we would generally describe any conventional photograph as "3D."

Nor would we describe a standard office photocopier or flatbed computer-scanner as "3D."

I don't understand your point here.
