Customers pay by scanning their faces in front of
a 3D camera attached to the point - of - sale booth, and punching in their phone number for added security.
I did this once with walrus where we
attached a
camera to the tusk of the animal, another time with the bowhead whale using a suction cup
attaching a
camera to the back of the whale, and yet again more recently with my
3D Polar Bear film
attaching a
camera to a female polar bear.
