While I don't doubt that is one use of the technology, I'd have to see
the details of the implementation before I'd believe that the hand
geometry from two fingers would be sufficient to uniquely identify

What is far more likely in my mind is Disney's ongoing desire to
prevent multiday passes and resort passes from being used by more than
one individual. I suspect that Disney ties a hash function of a few
points from the hand to the serial number of the pass.

Try to use the pass by someone else and the odds of the hash being the
same are sufficiently high enough to be detected ...
