I don't suppose anyone here knows the answer, but claims of matching accuracy like this make me wonder why basic touch ID so often fails and I need to delete my fingerprints and re-enroll. I always figured it was because of rock climbing tearing up my fingers and making the prints gradually different enough that they no longer match. Is it really easier to fool a fingerprint match than a face match? Or was I just wrong all along and the sensors suck? But if the sensors suck, why does deleting and re-enrolling work?
