Registering more than one finger with the Touch ID system is a sure-fire way of improving the overall accuracy of fingerprint recognition on your Touch ID-enabled iPhone or iPad.
If you have registered multiple fingerprints, it’s also helpful to name them (i.e. index finger, right thumb, etc.), as one of our recent tutorials explained.
Naming a fingerprint is super useful, for sure.
But in its typical fashion, Apple’s gone one step further: though most people will be aware of this, novice users may be oblivious to the fact that they can easily highlight in the list of registered fingers a finger that Touch ID matches.
How to quickly identify saved Touch ID fingerprint
1) Launch Settings on your iPhone or iPad.
2) Tap Touch ID & Passcode and type in your passcode to access this section.
3) Touch the Home button with one of your enrolled fingers. The matched fingerprint in the list will be highlighted briefly, as shown top of post.
Tip: To rename a saved finger, tap its default name in the list and then type a new one.
Aside from registering multiple fingerprints with Touch ID, you can actually use this feature to improve the accuracy and reliability of fingerprint recognition on a Touch ID-enabled iPhone or iPad.
Though not a documented feature, if you keep touching the Home button with one of your enrolled fingers at a slight angle, or curve the finger to the side or slide it up a bit more on the Home button so that the Settings app barely highlights it, iOS will use that data to enhance your fingerprint profile, improving Touch ID accuracy as a result.

Speaking of Touch ID, make sure iTunes & App Store is turned on under Settings → Touch ID & Passcode if you want to use your fingerprint instead of your Apple ID password for making purchases in the iTunes Store, App Store and iBooks Store.
