The Loop shared a great tip from Twitter user @TypistX with everyone this morning, and we wanted to share it with out readers. It covers a way to verify which fingers you’ve scanned for use with Touch ID on your iPhone 5s.
While this may sound silly at first blush, unless you’ve named each scanned finger to something like “Right Thumb,” or “Left Index Finger,” this will come in handy to let you know which fingers you’ve scanned.
On your iPhone 5s, just go to: “Settings” -> “General” –> “Touch ID & Passcode” –> “Touch ID.” (Note: If you’re already running the latest iOS 7.1 Beta on your iPhone 5s, you’ll need to go to: “Settings” -> “Touch ID & Passcode.”)
If you haven’t renamed your scanned fingers, you’ll see a list of scanned digits (Finger 1, Finger 2, etc.) Now place one of your scanned fingers on the home button. Touch ID will automatically scan your finger and look for a match. If it finds a match, the name of the scanned finger will be highlighted in the list.
Now would be a good time to rename that selection to a more descriptive name. Just tap the name of the fingerprint that was highlighted, and you’ll be able to rename your fingerprint. (You can also delete it, if you’d like.)
The Loop reader “BC2009” left this comment, we haven’t tried it yet, but it looks like a great tip:
A MUCH MUCH more important hidden feature of this screen is that you can use this screen to over-train your iPhone 5s with your fingerprints. If you have larger fingerprints you will find that after normal training the iPhone 5s may only have part of your finger registered (e.g.: the very tip versus the heel versus the sides).
However, from this screen you can keep tapping your finger to find the parts it recognizes and the parts it does not. Move your finger so it recognizes it and then slightly move your finger so that a part it previously did not recognize is also included. The iPhone 5s will learn those additional parts of the same finger. Once recognizes the additional region, you can move it a little more to include a part not previously recognized. Eventually, the entire surface of your fingerprint from the heel of the fingerprint, to the tip to the sides will be registered.
I’ve done this with my four registered fingers and it no longer matters which part of my finger I use and from which angle I use it.
