Because fingerprint readers are so 2003, the Snappy Face Recognizer uses your unique natural handsomeness as a password to log into your computer. The 1.3 megapixel camera snaps a few shots of you to compare to whenever you try and authenticate on your machine.
You could probably use the Face Recognizer as a regular webcam when it's not guarding your PC. Then again, with the right software, you could probably use a regular webcam to do authentication too. That is, if you don't suddenly gain 50 lbs and it can no longer recognize you.
Available for $98.
