If you own an iPhone 5s, give this a try. In the Settings app:
General > Touch ID & Passcode > Touch ID
You’ll see a list of your previously scanned fingers (Finger 1, Finger 2, etc.) Now place one of your scanned fingers on the home button. Touch ID will scan your finger and attempt to find a match. If it does, it will highlight that finger in its list.
This might seem frivolous, but it’s useful for verifying the fingers you’ve scanned. A nice touch, Apple.

UPDATE: Loved this comment from BC2009:
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.

You can also name the fingers after you’ve added them. Click “Edit” in the upper righthand corner. Not only will it let you delete fingerprints you’ve previously taught Touch ID, but you can tap on say, “Finger 1” and the keyboard will display for you to edit its name. Handy for saying “Finger 1” is “Right Thumb” and “Finger 2” is “Left Thumb”
from the “General > Touch ID & Passcode > Touch ID” screen? when i tap and it recognizes the print, it highlights the print in the list. but if its a miss, nothing is selected. to me that indicates that the only thing this screen does is authentications to highlight a match.
what makes you believe it’s recording new print data from this screen?
“A nice touch, Apple.” No pun intended?
According to Apple (see the security white paper) the sensor is constantly expanding and refining your fingerprint map. No need to make a big effort to do this.
I can verify this to be true. I saw it first on TWiT Security Now episode 440. Steve Gibson discovered this by accident and I’ve employed the same method, and demo this often when I sell the iPhone 5s at Sam’s Club where I currently work. There’s no documentation from Apple as of yet, but if you slowly “walk” your finger to an unregistered part in the Touch ID settings page, it will begin to recognize this part. Here’s the YouTube link to the Security Now episode.
Here’s the relevent text from BC2009:
“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 and tap again.”
But this screen provides instant feedback to you as to which parts of your finger are and are not registered.
YES. This it the best tip ever.
The old idea that “you should enter the same finger as several separate fingerprints” just seemed to confuse things after a while.
I also have to assume that Touch ID has been much improved in iOS 7.1.
ya i read that, but it doesnt strike me as anything other than some guy saying something on the interwebs.
i still dont follow how you believe it knows that the non-authenticated (un-registered) sample given is in fact part of just one of the 5 possible prints on file. it sounds like youre saying it’s just going to append it to the last-sucessfully-authenticated print, but i dont follow that leap.
