Arduino Fingerprint Computer Password Alternative

Hello, I was wondering wether or not I can interface a arduino, mini or nano, and make it a computer unlocker. My computer is a desktop, so it would be stationary. I use mac OSX. What would be needed to do a project like this? I am thinking about using AdaFruit's easy serial fingerprint scanner: Fingerprint sensor : ID 751 : $49.95 : Adafruit Industries, Unique & fun DIY electronics and kits Thanks In advance.

You sure you don't work at Adafruit....just trying to spread the word?

I ask because, if you read the whole description on the link you gave, you'd find links to -
— Arduino library

— A full tutorial on how to use it like you want

I do not work at adafruit, and I was wondering how I would use the library to unlock a computer.. Python or something?

I'm sure there are a ton of other ways to do it (probably google-able), but...

One way could be to use in conjunction with this

(Or just with Arduino alone) to act as a keyboard and send like a 72 Bit password needed to unlock your computer when it reads "authorized" fingerprints?
