These would be great if they were combined with another input for remote release i.e. fingerprint, code and opened remotely by an occupant.
Just seen this:
Double action fingerprint and access code security door lock for your office, business or home.
Very good value for money. You can open the lock with either a finger print or pin code or both. and there is also a standard key for the lock as well.
Finger print lock
If you do decide to buy don't forget to check that its suitable for your door, ie check which side your hinges are on etc.

They certainly seem cheap enough.
My experience of fingerprint recognition hasn't been great, my car uses it, but when its really cold, it doesn't read properly until I'm a bit warmer. Audi recommend breathing onto your finger if it won't read straight away.
And today, because I was doing DIY all weekend, my fingerprints are a bit knocked about, so I can't use my forefinger or thumb. Luckily I've scanned all the fingers on my left hand, so can keep trying them until one works!
Also had fingerprint recognition on my PDA some years ago, that worked intermittently, up to the point where I caught my finger in a router blade spinning at 11,000 rpm (ouch), and after that it never knew who I was!
ISTR, there was a problem with some of them, too, whereby they didn't clear memory between reads & could be tricked into using the last image rather than insisting on a new one each time - no idea if all of them were like this, and presumably a software update would have fixed it ?
I have a finger print lock as access to the node 0 room. What I did was to register the same finger about 10 times, in slightly different positions. This helped with the unit recognising my finger, almost all the time. The times when it doesn't its usually because my finger is a bit dry.
