When I saw (what I assume is) the underlying work presented about 6 years ago (by the inventor), he said you could ensure it was a real living iris by stimulating it with light and monitoring how it reacts - the check test worked regardless of pupil size as the iris just shrinks when the pupil is enlarged, so the pattern remains the same.
ISTR the test used a Gabor function on the scanned pattern, and it worked when there was the iris occupied about 80 pixels or more in diameter.
