There aren't a lot of uses for a biometric fingerprint scanner if you're not working for the government or police force. But if you are, well, your iPod Touch just got tax deductible.
The FbF MobileOne from Fulcrum Biometrics turns your iPod Touch into a full-fledged fingerprint scanner, letting you scan in prints, send them wirelessly and store them locally. That way, you can easily scan perps at a crime scene and then go back to playing Tiny Wings in the squad car on the same device. What's not to love about that?
