## Short answer

**An iPhone ignores an NFC business card for one of a short list of reasons, most often an older model, a locked or dark screen, the camera or Wallet being open, or the card held to the middle of the phone instead of the top. Less often, the tag holds a vCard or nothing rather than a web link, the chip is dead, or its page is down.** Check them in that order. If the tap still fails, show a QR code: the iPhone camera reads it with no settings to change.

## Why won’t my iPhone read the NFC card?

Because the phone was not reading at that moment, far more often than because the card is faulty. Here is the whole checklist, most likely cause first.

The tap has no error message. When it fails, nothing appears at all, so both of you are left guessing. The causes below are ordered by where to look first: the phone’s own state is free to check and most often the answer, and a dead chip is the last thing to blame.

1. **Check the iPhone can read tags on its own** — Apple says iPhone XS and later read tags in the background. An iPhone 7, 8 or X has to open the NFC Tag Reader in Control Centre first; without it, nothing happens.
2. **Wake the screen and unlock the phone** — Background reading only runs while the phone is in use. On a locked iPhone the notification appears but asks for an unlock, and after a restart it will not read until the phone has been unlocked once.
3. **Close the camera, Wallet and Apple Pay** — Apple lists the camera in use, Wallet or Apple Pay in use and Airplane Mode as times the screen is on and background reading is still off. Someone who opened the camera to scan your QR has switched NFC off by doing so.
4. **Hold the card flat to the top of the back** — The reader is at the top of the iPhone. Hold the card near it and keep it still for a second or two; sliding it across the middle of the phone misses.
5. **Take away the case, the metal and the other cards** — Try again without a thick or metal case, away from a metal card holder, and with only one tagged card near the phone. Metal detunes an NFC antenna.
6. **Check what the tag actually holds** — A working business-card tag holds one URL record, starting https://. A vCard, plain text, a custom app link or a blank tag gives an iPhone nothing to show.
7. **Try a second phone** — If another recent iPhone, or an Android phone with NFC switched on, also reads nothing, suspect the chip. If it opens a page, the problem was the first phone.
8. **Open the address in a browser** — If the tag reads but the page errors or loads slowly, the tag is fine and the page is not. Type the address into Safari and fix it there.

If you are the one handing the card over, the first three steps are the other person’s phone, which you cannot see. That is why so many NFC cards carry a QR code on the back as well, and why we come back to it at the end. The wider trade-off between the two is in [NFC vs QR for business cards](https://cardr.co/blog/nfc-vs-qr-business-cards).

## Which iPhones read NFC tags on their own?

iPhone XS and later, according to Apple. Older NFC-capable iPhones can read tags, but only after the NFC Tag Reader control is opened from Control Centre.

[Apple’s Core NFC documentation](https://developer.apple.com/documentation/corenfc/adding-support-for-background-tag-reading) (read 23 September 2026) puts it plainly: “iPhone XS and later support background tag reading.” Background reading is what makes a business card work: the phone reads the tag without an app open and shows a notification to tap. Apple’s [iPhone User Guide model list](https://support.apple.com/en-euro/guide/iphone/aside/asd-nfc-reader/15.0/ios) names the iPhone XR, XS, XS Max, the 11, 12 and 13 families and iPhone SE (2nd generation and later) as reading automatically, and says the iPhone 7, 7 Plus, 8, 8 Plus and X need you to “turn on NFC Tag Reader in Control Center”. That list was written for iOS 15 and stops at the 13; later iPhones fall under “XS and later”.

On a supported iPhone there is no NFC switch to turn on. That surprises people coming from Android, and it means “is NFC enabled?” is the wrong question on an iPhone. The right questions are about what the phone is doing.

**The screen has to be on, and the phone in use.** Apple says the system reads tags in the background “only when the user’s iPhone is in use”, and its [design guidelines](https://developer.apple.com/design/human-interface-guidelines/nfc) say it looks for tags “whenever the screen is illuminated”. If the phone is locked, it shows the notification but asks for an unlock before opening anything.

**Some things switch it off even with the screen on.** Apple lists them: the device has never been unlocked since it started, an app’s NFC scanning session is in progress, Wallet or Apple Pay is in use, the camera is in use, or Airplane Mode is on. The camera one catches people out constantly. Someone who has already opened their camera to scan your QR code has, by doing that, stopped their phone reading your tag.

## Where do you hold the card?

Against the top of the back of the iPhone, flat and still. The middle of the phone, where most people instinctively tap, is the wrong place.

Apple does not publish an antenna diagram for tag reading, but it is consistent about where the reader is. Its [Apple Pay instructions](https://support.apple.com/en-gb/102626) say to “hold the top of your iPhone near the contactless reader”, and NFC tag reading uses the same radio. Apple’s guidelines also say the phone only needs to be in close proximity and does not need to touch the tag, and tell developers to say “hold near” rather than “tap”. In practice: card flat, top third of the back, hold it for a moment instead of bumping it.

**Cases.** Apple documents nothing about phone cases and tag reading, so there is no official list of cases that work. The test is simple: if it fails, take the case off and try once more.

**Metal cards and metal wallets.** Here there is real physics. NXP, who make NFC chips, explain in [application note AN11755](https://www.nxp.com/docs/en/application-note/AN11755.pdf) (read 23 September 2026) that metal close to an NFC antenna picks up eddy currents that absorb power and detune the antenna, and that a ferrite layer is needed to shield it. That is why a metal business card that works has its chip in a non-metal window or on a shielding layer, and why a plastic card kept in a metal card case, or pressed against a metal phone case, can read badly or not at all. Two tagged cards stacked together can confuse the read as well: hold out one.

## What should the tag hold?

One web link. An iPhone reading in the background only acts on a URL record, and a business card tag holding anything else will look dead.

Apple’s documentation is specific. When an iPhone reads a tag in the background, it looks in the tag’s NDEF message for a URI record, uses the first one if there are several, and only acts if it is a universal link or one of a short list of schemes: web links (http and https), mailto, sms, tel, FaceTime, Maps and HomeKit setup codes. It does not support custom URL schemes. There is no vCard, plain text or contact record on that list.

So a tag that a seller filled with a vCard, or wrote with a link in an app-only format, can read perfectly well on an Android phone and do nothing at all on an iPhone. A blank or unformatted tag, never written, does nothing on either. If you can, rewrite the tag with a single https:// address for your card page; most NFC business cards allow it through the seller’s app or a free NFC writer app, and our [NFC business cards](https://cardr.co/nfc-business-cards) page covers pointing one at a Cardr address. If you want the contact to save straight from a code instead, that is what a [vCard QR code](https://cardr.co/blog/vcard-qr-code-guide) is for.

Symptoms, causes and fixes, together:

NFC business card on iPhone: symptom, likely cause, fix

| What you see | Likely cause | Fix |
| --- | --- | --- |
| Nothing at all, on an iPhone 7, 8 or X | No background tag reading on these models | Open NFC Tag Reader in Control Centre, or show a QR code |
| Nothing at all, on a recent iPhone | Screen off, camera, Wallet or Apple Pay open, or Airplane Mode | Wake the phone, close the camera and Wallet, try again |
| Nothing, just after a restart | Phone not unlocked since it started | Unlock once, then try |
| Notification appears, nothing opens | Phone is locked | Unlock when asked |
| Works sometimes, not others | Held to the middle, or moved too fast | Hold flat to the top of the back, still, for a second |
| Fails in a case or near a card holder | Metal or a thick case in the way | Remove the case, move away from metal, one card at a time |
| Opens on Android, nothing on iPhone | Tag holds a vCard, text or custom link, not a URL | Rewrite the tag with one https:// address |
| Nothing on any phone | Blank tag, or damaged chip | Write the tag; if it will not write, replace the card |
| Page opens with an error | The address is wrong or the page is down | Open it in a browser and fix the address or the page |

iPhone behaviour from Apple’s [Core NFC documentation](https://developer.apple.com/documentation/corenfc/adding-support-for-background-tag-reading) and [Human Interface Guidelines](https://developer.apple.com/design/human-interface-guidelines/nfc); metal from NXP [AN11755](https://www.nxp.com/docs/en/application-note/AN11755.pdf). All read 23 September 2026.

**A dead chip.** Apple offers no way to diagnose one, so the honest method is elimination. If two different phones that do read other NFC tags both get nothing from yours, and nothing metal is nearby, the chip or its antenna is probably damaged; a crease or crack across the card can do it. Replace the card; a tag cannot be repaired.

**The page is down.** If the notification appears and then Safari shows an error, the tag worked. The address it holds no longer loads, has a typo, or points at a service you have left. Open the same address yourself and fix it at the source, or rewrite the tag.

## What if they have an Android?

Check NFC is switched on. Unlike an iPhone, Android has a setting for it, and it is often off.

[Google Wallet Help](https://support.google.com/wallet/answer/14186809?hl=en-GB) (read 23 September 2026) says to open Settings, search for “NFC” and make sure it is on, and that the steps differ between devices. Android’s [developer guide](https://developer.android.com/develop/connectivity/nfc/nfc) says phones are “usually looking for NFC tags when the screen is unlocked”, so the screen matters there too. On recent versions a web-link tag opens the link directly, and the same guide says that from Android 17 it shows an “open link” notification to tap first. Where the antenna sits varies by manufacturer, so try the middle and the top of the back. More on Android and digital cards generally is in our [Android guide](https://cardr.co/blog/digital-business-cards-android).

## When should you stop tapping?

After one retry. If the tap fails twice, show a QR code: it asks nothing of their phone but a camera, and nobody has to troubleshoot anything mid-conversation.

Every cause above lives on the other person’s phone or in your card’s chip, and you can fix neither while they are standing in front of you. A QR code has none of those dependencies. [Apple’s iPhone guide](https://support.apple.com/en-gb/guide/iphone/iphe8bda8762/ios) (read 23 September 2026) has you open Camera, point it at the code and tap the link that appears, with no setting to turn on and no model cut-off to worry about. Android phones read them from the camera or a scanner app, depending on the make.

Cardr sells no NFC hardware, so we have no card to replace yours with and no reason to talk you out of one. What a Cardr does is put a QR code on your phone: your card is a [signed Apple Wallet pass](https://cardr.co/apple-wallet-business-card) that shows a code, and scanning it opens your page at cardr.co/yourname, where one tap on Save saves you to their contacts and one more sends their details back. Keep your NFC card for the moments it works, and have the code one swipe away for the moments it does not. The card, the pass and the QR code are free. There is more on choosing between the two on our [QR codes and NFC](https://cardr.co/qr-code-business-card) page.

One thing a Wallet pass cannot do is replace the tag. Apple’s [Wallet pass documentation](https://developer.apple.com/documentation/walletpasses/pass/nfc-data.dictionary) describes a pass’s NFC payload as something the device passes to an Apple Pay terminal, not to another phone, and says adding NFC to a pass “requires a special entitlement issued by Apple”. A digital card in Wallet is shared by its code.

## Questions, answered

### Why does nothing happen when I hold an NFC business card to my iPhone?

Usually because the phone is not reading at that moment. iPhone XS and later read tags only while the screen is on and the phone is in use, and not while the camera, Wallet or Apple Pay is open, in Airplane Mode, or before the first unlock after a restart. Hold the card to the top of the back, not the middle.

### How do I turn on NFC on my iPhone?

On iPhone XS and later you do not: there is no switch, and background tag reading is always available while the phone is in use. On an iPhone 7, 7 Plus, 8, 8 Plus or X, Apple says to turn on NFC Tag Reader in Control Centre before holding the tag near the phone.

### Where is the NFC reader on an iPhone?

At the top of the phone. Apple’s Apple Pay instructions say to hold the top of your iPhone near the reader, and tag reading uses the same NFC radio. Hold the card flat against the top third of the back and keep it still for a moment rather than tapping the middle.

### Why does my NFC card work on Android but not on iPhone?

Most often because of what the tag holds. An iPhone reading in the background only acts on a URL record: a web link or one of a few schemes such as tel or mailto. A tag holding a vCard, plain text or a custom app link can open on Android and show nothing on an iPhone. Rewrite it with an https:// link.

### Do phone cases stop NFC business cards working?

Apple does not document which cases affect tag reading, so there is no official answer. Metal is the known problem: NFC chip maker NXP explains that metal near an NFC antenna detunes it. If a tap fails, try once without the case and away from any metal card holder before blaming the card.

### How do I know if my NFC business card is broken?

By elimination, because Apple offers no diagnostic. Try two different phones that read other NFC tags, with the screen on and nothing metal nearby. If neither shows anything, the chip or antenna is probably damaged. If one shows a notification but the page errors, the chip is fine and the web address is the problem.

### Can an Apple Wallet business card work over NFC?

Not as a tap between two phones. Apple’s documentation describes a Wallet pass’s NFC payload as going to an Apple Pay terminal, and says NFC on a pass needs a special entitlement from Apple. A Wallet business card, including a Cardr, is shared by the QR code on the pass.
