Homebrew PCBs

I didn't know there is such a thing, and they probably also went with
what they already knew. But i don't doubt there are better ways to
make those fake fingers.

What was really amazing is that the printout on paper worked on the
good quality lock which has "never been defeated" according to the
manufacturer. I mean that takes 10 minutes with a simple office
scanner and printer, and you can probably find the fingerprints you
need to copy close by.

It was also interesting to see which tricks worked on the ultrasonic
and IR motion detectors, but none involved a PCB.

If you think about it, carrying a RFID key, keycard, or even a simple
barcode tag would be safer than a fingerprint lock.
