Perhaps it's a 3d image or each eye, or at least stereoscopic. I looked on their site but it was unsurprisingly light on detail.
With 3d images the system could perhaps detect the curvature of the eyeballs, making it harder to fake. Or perhaps the imaging system is looking for details or features that would be difficult to print, say things only visible in IR.
Totally agree with earlier sentiments that biometrics should only serve as a user ID. Never a password.
Confirm identity, not clearance.
