If you're using a case or screen protector, make sure it doesn't cover the Touch ID sensor or the surrounding ring. Go to Settings > Touch ID & Passcode and make sure that iPhone Unlock or iTunes & App Store is on, and that you've enrolled one or more fingerprints. Try enrolling a different finger.
Tap Settings > Touch ID & Passcode, then enter your passcode. Tap Add a Fingerprint and hold your device as you normally would when touching the Touch ID sensor. Touch the Touch ID sensor with your finger—but don't press—so the device can begin recognizing your fingerprint.
The passcode has not been used to unlock the device in the last six days. Your fingerprint has not been used to unlock the device in the last eight hours. You have just powered up (or rebooted) your device. Your device has not been unlocked for more than 48 hours.
