I'm not entirely sure I believe that explanation. It could be an impendance measurement, they can determine a lot of weird tissue properties that might be individual (I had a teacher on my biomedical engineering course who was the local guru on this area; he used it to check the condition of transplanted kidneys). My guess is that it is a hand/fingerprint scanner of some kind.
Or maybe EvMick's grandfather was right and it really is alien technology :-)
