The c't article along with Matsumoto et al's "gummy bear" paper indeed started much of the then-interesting biometric device testing, something which seemingly the makers of the equipment didn't think of themselves.

Myself and others did a project on this when I was in college, and we managed to easily make moulds out of play-dough as the referenced article, along with other stuff.
