Hello there, Oharadva.
The following Knowledge Base article provides some great information as well as steps for troubleshooting Touch ID:
iPhone 5s: Using Touch ID
http://support.apple.com/kb/HT5883
This particular section deals with troubleshooting:
- Verify that you are using the latest version of iOS.
- Ensure 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.
- Tap Settings > General > Touch ID & Passcode > Touch ID and verify that:
- iPhone Unlock or iTunes & App Store is enabled.
- One or more fingerprints have been enrolled.
- If one finger isn't working, tap Edit in Settings > General > Touch ID & Passcode > Touch ID > Edit to delete and then reenroll the finger.
- If that finger still isn't working, try enrolling a different finger.
- If you are unable to 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 may 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.
Thanks for reaching out to Apple Support Communities.
Cheers,
