Looking for an app to read fingerprints and store using Touch ID - not a prank

[Michael Anthony]

I'm looking for an app that uses the actual touch ID sensor to read a fingerprint and then store it - not to unlock anything - and not one of the ridiculous prank apps out there. Can't believe I've had to resort to asking around, I've looked for a fair while.

Probably because something like that doesn't exist?

What you want won't be possible. The Touch ID sensor does not pass fingerprint data to the computer, and thus you will never see an app that records fingerprints.
