How can i make a fingerprint reader to unlock a door? (Preferably under £20)? Answered

Hey,
   I'm wanting to make a fingerprint scanner to go on a hidden door (made into a bookcase), the hiding of the scanner isn't a factor i'm worrying about at the moment - But i can't afford to pay out like £50 just for a scanner!
Or if you can think of any alternatives to this, that would be great too! (:
Thanks!

.  Apparently you are in the UK so YMMV, but Google tells me that the devices can be had for as little as $20 (~£14) online. You should be able to find a similar deal on your side of The Pond.
