Isn’t it annoying when you pop your finger on the Touch ID button of your iPhone or iPad only to have it rejected?
Here’s a quick and simple way to improve the accuracy and reliability of Touch ID.

It’s really simple – since iOS allows you to register multiple fingers, what you do is register the same finger multiple times. By doing this you can press your finger (or thumb) on the sensor in different ways so it gets registers from a variety of angles.
Another thing you can do is since dirty of damp fingers fail to pass muster with Touch ID because it sees them differently to clear, dry fingerprints, you can also register a finger when it’s damp (not soggy or wet) and dirty.
This can be a real timesaver if you have sweaty fingers or operate your iPhone or iPad with dirty hands.
To do this click on Settings and go to Touch ID & Passcode . You’ll be prompted to enter your PIN or passcode and from there you can add more fingerprints by clicking Add a Fingerprint.
You can register up tfive prints, and you can give each enrolled fingerprint a unique name (which might come in handy for fine-tuning this trick).
