No fingerprint lock for me

Before seeing this science programme, I was considering getting a fingerprint lock for my house in order to avoid having to carry around a key all the time. But seeing how easy a fingerprint can be forged (make it visible using speed glue, take a digital picture of it, print it on a transparent slide, make a positive of the print using wood glue - that's it), I am not interested any more. It's just like leaving carbon copies of my key all over the place - thank you, Chaos Computer Club!
