iPhone 5s: Using Touch ID

Resolving issues with Touch ID

1. Make sure that you're using the latest version of iOS.
2. Make sure that your fingers and the Home button are clean and dry.*
   Note: Cover the Home button completely. Don't tap too quickly, don't press down hard, and don't move your finger while Touch ID is scanning. Make sure that your finger touches the metal ring around the Home button.
3. If you're using a protective case or screen protector, it must leave the Home button and the surrounding ring completely unobscured. If it doesn't, remove the case or screen protector and try again.
4. Tap Settings > Touch ID & Passcode and verify that:
   • iPhone Unlock or iTunes & App Store is on.
   • You enrolled one or more fingerprints.
5. Try enrolling a different finger.
6. If you can't enroll any of your fingers, take your iPhone 5s to an Apple Retail Store, Apple Authorized Service Provider, or contact AppleCare for further assistance.

* Moisture, lotions, sweat, oils, cuts, or dry skin might affect fingerprint recognition. Certain activities can also temporarily affect fingerprint recognition, including exercising, showering, swimming, cooking, or other conditions or changes that affect your fingerprint.

I hope this information helps ....
