Follow these steps. Try using Touch ID after each step:

1. Make sure that you have the latest version of iOS.
2. Make sure that your fingers and the Home button are clean and dry.* For the Home button, use a clean, lint-free cloth to wipe off any dirt or debris.
3. Your finger should cover the Home button completely, touching the surrounding metal ring. While Touch ID is scanning, you shouldn't tap too quickly or move your finger around.
4. If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring.
5. 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.
6. Try enrolling a different finger.

Automatically detects whether it is a QR code or UPC barcode. It's easy to trick your phone's fingerprint scanner. Here's how we should fix it. Early last week, I was setting up fingerprint sensors on my new iPhone. That's when my brother, @Prateek, came up with an idea to test these mobile fingerprint sensors. The test was to scan his finger along with mine at the time of fingerprint setup.

If the previous steps didn't help, you see 'Failed—unable to complete Touch ID setup', or either of the following happen when you go to Settings > Touch ID & Passcode, take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support:

• You can't turn on Touch ID
• Touch ID is dimmed or grayed out

If you need to enter your passcode

You might need to enter your passcode or Apple ID instead of using Touch ID in these situations:

• You just restarted your device
• Your fingerprint isn't recognized five times in a row
• You haven't unlocked your device in more than 48 hours
• You just enrolled or deleted fingerprints
• You're trying to open Touch ID & Passcode in the Settings menu
• You used Emergency SOS.

* 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.

Where is the Touch ID sensor?

The Touch ID sensor is either in the Home button or—on iPad Air (4th generation)—the top button. When you follow the steps below, the onscreen instructions will tell you which button to use.

Set up Touch ID

Before you can set up Touch ID, you need to create a passcode for your device.* Then follow these steps:

1. Make sure that the Touch ID sensor and your finger are clean and dry.
2. Tap Settings > Touch ID & Passcode, then enter your passcode.
3. Tap Add a Fingerprint and hold your device as you normally would when touching the Touch ID sensor.
4. Touch the Touch ID sensor with your finger—but don't press. Hold it there until you feel a quick vibration, or until you're asked to lift your finger.
   
5. Continue to lift and rest your finger slowly, making small adjustments to the position of your finger each time.
6. The next screen asks you to adjust your grip. Hold your device as you normally would when unlocking it, and touch the Touch ID sensor with the outer areas of your fingertip, instead of the center portion that you scanned first.
