If someone wants your fingerprints they already have them.

  Therefore it's a good idea to use your fingerprints for authentication?

    Good point, but it's probably at least as secure as a four digit pass-code that everyone around you can see.

      Will you use different fingerprints for different systems? What do you do when your fingerprint gets compromised?

  What else does this magical sentence work for? I want a million dollars.

  Governments do, but ordinary criminals don't. Yet. This is a very important enabling technology not because it's new, but because it'll gain widespread use in a short time.

  Sure, if someone wants your credit card number, they already have it too. They just follow you around with a telephoto lens and take a photo when you remove your credit card to use it. But if someone just wants a few thousand credit card numbers, and not yours specifically, that's when an ounce of caution can go a long way towards protecting yourself.
