Fingerprint sensor Door Locks are getting affordable enough to not only secure data centers but also your room.

FS Locks told us that their FS Bio Lock is the their best seller. The price for this fingerprint lock is only $199.00. I have found the same lock under different names on other stores. It looks like this model is the most common on the market.

If you have lots of trusted friends this lock is for you. You can register up to 138 people.
Other features of the fingerprint lock are automatic locking, indoor or outdoor use, one year battery life, pin code access and key access. This lock uses an optical sensor with 0.3 mega pixel resolution.
If you rather use RFID to access your digs, have a look at this lock.
