The question we hear most from anyone considering an NFC card is simple: "Will it work on every phone?" The short answer: on most modern phones, yes, but not on all of them, and a few small details make all the difference. This guide walks through those details so you know what to expect, and what to do if a card doesn't open on the first try.
First: how does a phone read the card?
Every NFC phone has a small antenna inside, and every NFC card has a chip with no battery. When the card comes close to that antenna, the chip wakes up for a moment and hands the phone a link. A notification appears, and it opens the page in the browser. The range is very short, usually a few centimetres, so the card needs to be near the right spot on the phone, not just anywhere.
iPhone: what you need to know
Recent models
Recent iPhones, from the iPhone XS and iPhone XR onwards, read NFC cards automatically in the background. No app needs to be opened; the screen just needs to be on when you bring the card close.
Older models
On some older models, such as the iPhone 7, 8 and X, background reading isn't available. On those phones, people may need to open the NFC reader in Control Center where their phone offers it, or simply scan the QR code on the card.
Where to tap an iPhone
The iPhone's NFC antenna sits at the top of the phone. Hold the card against the top edge of the back, not the middle or the bottom.
Things that can get in the way on iPhone
- The screen must be on. If it's fully off, the card may not be read.
- If the camera is open or Apple Pay is in use at that moment, background reading can pause.
- After the tap, a small notification appears at the top of the screen, and it needs a tap to open the page.
Android: what you need to know
Does every Android phone have NFC?
Many mid-range and high-end Android phones include NFC, but not all of them. Some budget models don't have an NFC chip at all. For those, the answer is the QR code.
Does NFC need to be switched on?
On Android, NFC can be turned on and off in settings. If it's off, the phone won't read the card. You'll usually find it under "Connections" or "Connected devices", or as an NFC tile in the quick settings panel.
Where to tap an Android phone
Antenna placement varies between models, but it's usually around the middle of the back, near the camera. If the card isn't read straight away, move it slowly across the back of the phone until it is.
Why didn't the card open? Common causes and fixes
If you tapped and nothing happened, it's usually one of these:
- Wrong spot: on iPhone, try the top edge; on Android, try the middle of the back.
- Screen off or fully locked: wake the screen and try again.
- NFC switched off on Android: turn it on in settings.
- A thick or metal case: very thick cases, or ones with metal plates or magnetic mounts, can weaken the signal. Try without the case.
- Moving too fast: hold the card near the phone for a second or two.
- The phone has no NFC: use the QR code.
Why the card should also carry a QR code
Because the point of the card is for everyone to reach your page, not only people with a particular phone. A QR code can be scanned by almost any phone camera and opens the same page. Having both means you never lose a contact because of their device, and you can also reuse the code on brochures, screens or your email signature.
Does the other person need an app?
No. Neither iPhone nor Android needs an app to read a card that holds a link. The card opens your page in the normal browser, and people save your contact straight from it. This is a big part of what makes the experience smooth, especially with people you're meeting for the first time.
How to test your card before using it with clients
Before an important meeting or an exhibition, take a minute to test:
- Try it on your own phone and on someone else's phone with the other operating system.
- Try the QR code as well.
- Open the page and check that your numbers and links are correct.
- Tap "Save contact" to see exactly how your name appears in contacts.
At Lamsa, every card is tested on iPhone and Android before delivery, but a quick personal check gives you extra confidence in front of clients.
The bottom line
NFC cards work on most recent iPhones and many Android phones, as long as they're tapped in the right spot and NFC is switched on for Android. For phones that don't support NFC, a QR code is the simple fallback that makes sure everyone can reach your page.
