Fingerprints

You've probably read that the iPhone 5S has a fingerprint sensor. You'll be able to use your fingerprint to unlock your phone and access Apple's App Store or iTunes. Using your fingerprint to unlock something isn't a new concept nor is it the first phone to implement the sensor.
Recently, there have been countless articles about how people have found ways to "break-in" or pass the fingerprint test. The response? People are genuinely surprised by the fact this could be done. I don't understand why since the concept of duplicating a fingerprint has been displayed in numerous movies. It would be much more interesting if someone extracted the fingerprint information from the iPhone though.
While it could be difficult to replicate someone's fingerprint without some prints and time, it's definitely not the end-all be-all security measure. It's just an added measure of security and provides more convenience and protection than the four digit passcode or pattern code. And it can't be the sole security measure for another reason: Not everyone has fingerprints; it's an extremely rare case though.
P.S. The photo above isn't enough to replicate my thumb print... Is that a N64 injury?
