Apple made the Touch ID fingerprint sensor work rather well (press Home button and hold; done). Samsung’s copycat version just tells everyone how much more work needs to be done to make biometrics a success. John Fontana:
In the Samsung case, its fingerprint scanner has a higher risk ratio than the iPhone in that it is paired with PayPal transactions. Apple doesn’t let its fingerprint technology wander off its own platform, which may be as much a statement on the technology as it is on Apple’s platform superiority complex… These are technologies in progress in terms of authentication methods, but the result is that a combination of contextual information may ultimately be the best way to determine that you are who you say your are. Of course, hackers will set in motion the test of time against all of these authentication ideas just as they have done in the past.
Apple’s Touch ID is paired with an iTunes account; good for music, TV shows, movies, and apps– all downloaded to the device.
Is it secure enough for banking and buying? Not yet (then again, how secure is the credit card you give to the waiter at a restaurant?).
