The video said you can use your fingerprint to make iTunes purchases. The guy in the video also said fingerprints are stored only on the phone's CPU, not iCloud or anywhere else. If that is the case, how do the systems on the other end know the fingerprint is valid? For functions other than unlocking the phone, does a fingerprint serve as direct authentication, or does it simply work to unlock an existing password?
