10 Tech How-To

How to Use NFC Tag Reader in iOS 14

Guide 10-36585 · Updated · Step by step

Starting with iOS 14, your iPhone can read NFC tags automatically without needing to open a separate app or scan from the Control Center. This guide walks you through the built-in NFC reading features, what you can do with them, and how to troubleshoot when things don’t work as expected.

What You’ll Need

  • An iPhone that supports background NFC reading: iPhone XS, XR, or newer (iPhone SE 2nd generation and later also work).
  • iOS 14 or later installed.
  • An NFC tag (NDEF formatted) – these are common in smart posters, product labels, or blank tags you can buy and program.
  • For writing tags, a third-party app like NFC Tools (free) or Shortcuts (built-in) can be used.

Step-by-Step

  1. Check your iPhone model and iOS version. Go to Settings > General > About. If your model is listed as compatible and your iOS version is 14 or later, you’re ready.
  2. Make sure NFC is enabled. There’s no toggle for NFC in iOS 14 – it’s always on. However, if you have a third-party NFC app that requires permission, make sure it’s allowed under Settings > Privacy > NFC & Reader Mode (if you see that option).
  3. Unlock your iPhone. For background reading, your iPhone must be unlocked (Face ID or passcode). If it’s locked, the tag won’t be read automatically.
  4. Bring the tag near the top back of your iPhone. The NFC reader is located near the camera module on the back. Hold the tag about 1–2 cm away, parallel to the back of the phone.
  5. Wait for the notification. Within a second or two, a banner will appear at the top of the screen, showing the tag’s content or a preview. Tap it to open the linked URL, text, or other data.
  6. If nothing happens, try moving the tag. Slide the tag slowly across the back of the phone, especially around the camera area. Sometimes the tag needs to be exactly in the right spot.
  7. For tags that don’t auto-read, use the Control Center. Swipe down from the top-right corner (or up from the bottom on older iPhones) to open Control Center. Tap the NFC Tag Reader button (a small icon with waves). Then hold the tag near the back – a scanner screen will appear and read it.
  8. If the tag contains a URL, Safari will open it. If it contains text, a preview will appear. If it contains contact info, you can add it to your contacts.
  9. To write to a blank NFC tag, use the Shortcuts app. Create a new automation or a shortcut that uses the “NFC” action. Then tap “Scan” to program the tag with a URL, text, or a shortcut trigger.
  10. Test with a known tag. If you’re not sure if your tag works, try a tag you know is NDEF formatted, like a smart poster or a business card with an NFC chip.

Common Mistakes

  • Holding the tag too far away. NFC has a very short range – usually less than 2 cm. If you hold it too far, it won’t read.
  • Keeping the phone locked. Background NFC reading requires the screen to be on and the phone unlocked. If it’s locked, nothing happens.
  • Using a tag that isn’t NDEF formatted. Some tags are raw or use proprietary formats. iOS only reads NDEF (NFC Data Exchange Format) tags.
  • Placing the tag on the wrong spot. The reader is at the top back, not the middle or bottom. Check your iPhone’s user guide for the exact location.
  • Expecting all tags to auto-open. Some tags are set to require a tap, especially if they contain sensitive data. You’ll need to tap the notification.

Tips

  • Use the Control Center reader for stubborn tags. The manual reader often works when background scanning fails.
  • Keep your iPhone’s case in mind. Thick cases or metal cases can block NFC. Remove the case if you’re having trouble.
  • Program your own tags for shortcuts. You can set an NFC tag to trigger a shortcut, like turning on lights or starting a timer – very useful.
  • Check if the tag is damaged. NFC tags are durable but can fail. Try another tag to isolate the issue.
  • Update iOS. Apple has improved NFC reliability in later updates, so keeping iOS up to date helps.

Troubleshooting

Nothing happens when I hold the tag to my iPhone. First, ensure your iPhone is unlocked and the screen is on. Then, try the Control Center reader. If that works, the tag might be in a location that’s hard to reach – try moving it. If the Control Center reader also fails, the tag is likely not NDEF formatted or is damaged. Test with a known good tag.

I get a “Tag Not Supported” message. This means the tag uses a format iOS can’t read (e.g., some Mifare tags). You’ll need a tag that’s NDEF compatible. Many blank tags sold for phones are fine, but check the product description.

The tag reads but doesn’t open the URL. Some tags require a confirmation tap. If the notification appears, tap it to open. If it still doesn’t open, the URL might be malformed – try rewriting the tag with a simple URL like “https://example.com”.

My iPhone is compatible but the Control Center reader is missing. On iOS 14, the NFC Tag Reader button is in Control Center by default. If it’s not there, go to Settings > Control Center > Customize Controls and add “NFC Tag Reader”.

Background reading only works sometimes. This can happen if the tag is placed at an angle. Try holding the tag flat against the back, directly over the camera area. Also, remove any magnetic or metal accessories.

Frequently Asked Questions

Q: Can I read NFC tags with my iPhone SE (2nd generation)?
A: Yes, the iPhone SE (2nd gen) supports background NFC reading with iOS 14. It has the same NFC chip as the iPhone 11 series.

Q: Do I need an app to read NFC tags?
A: No, iOS 14 has built-in reading. Just hold the tag near your iPhone. For writing or advanced actions, you’ll need an app like NFC Tools or the Shortcuts app.

Q: Can I write to an NFC tag with my iPhone?
A: Yes, using the Shortcuts app or third-party apps. The Shortcuts app allows you to write a URL or a shortcut trigger to a blank tag.

Q: Why does my iPhone not read some NFC tags?
A: The tag might be in a non-NDEF format, damaged, or too far away. Also, some tags are locked or have security features that prevent reading.

Q: Is NFC always on?
A: Yes, there’s no toggle to turn it off. It’s always listening, but it only activates when a tag is in range and the phone is unlocked.

Q: Can I use NFC to pay with Apple Pay?
A: Apple Pay uses a separate secure element and works even when the phone is locked. That’s different from reading NFC tags, which requires the phone to be unlocked.
