For most of us when we want to establish a tactile identification, usually go through the initial process of adding a mark or two on the iPhone or iPad and not think more beyond that. Perhaps the process is repeated again with the same finger a few times to unlock the Touch ID more reliable.
On the other hand, for users who have added multiple different fingers to touch ID sensor, if they have not identified, they may find the "fingerprint 1" and "fingerprint 2" are not the most descriptive names on the planet and you have no idea what name corresponds to their fingerprints that come into contact with the touch ID.
Fortunately there is an easy way to identify fingerprints on the Touch ID and highlight them with a simple trick.
Highlight and identify fingerprints with Touch ID in iOS:
- Open the application settings and go to "Touch ID & Access Code".
- Scroll down to the section 'Fingerprints' of the configuration screen.
- Now place your finger on the fingerprint identification sensor to highlight the corresponding fingerprint within the parameters of tactile identification.
Matching fingerprints briefly highlighted in gray, fading from the inside out, making it an easy and immediate identification when an impression is comparable to that in the Touch ID.
This is a great trick to help improve the function, removing a fingerprint of touch if it is not working well, and then a fingerprint will add a couple of times to make more reliable the ability to unlock. This is particularly useful for use Touch ID in cold climates where the skin is dry, but can be applied to wet climates.
