Howdy,
I watched Adafruit's weekly "Ask An Engineer" show last night and was surprised to see this intriguing new product:
Optical Fingerprint Sensor
http://ladyada.net/products/fingerprint/
Their New Products segment gives a nice demonstration:
In truth, it's just a TTL serial device so it could be used with any microcontroller. However, Adafruit has written a nice Arduino library:

Anyone have a project that fingerprint scanning would be a nice feature for?
I have a Arduino-powered character LCD device in my cube which displays my status, so maybe I could add fingerprint scanner to provide certain individuals with private messages. For example, the current generic status might be 'in design review meeting' but if one of my buddies scans in, it displays 'at the pub on the corner - come join me'.
Cheers,
Drew
