From Raspberry Pi Tutorials:
Not only in Hollywood films, fingerprint readers are seen more and more frequently. Such modules are often installed in home surveillance systems and are used for the simple but secure verification of persons. With such a Raspberry Pi Fingerprint Sensor you can also implement some other projects, such as secured locks.
One of the advantages is that passwords and / or number codes can be completely omitted. Although this is still possible, but it’s a lot more comfortable without. This tutorial is about the connection as well as the reading, saving and verifying of imported fingerprints.
