An NFC business card contains a tiny chip and antenna. When you hold it near a smartphone, the phone powers the chip wirelessly, reads the web link stored on it and opens your digital business card in the browser. No app, no pairing, no battery — the whole exchange takes about a second.
What NFC is, in one minute
NFC (Near Field Communication) is a short-range wireless technology — the same one behind contactless payments. It only works at very close range, typically within a few centimetres, which is why you tap rather than wave.
The chip in a business card is passive: it has no battery. The phone's NFC reader creates a small electromagnetic field that powers the chip just long enough for the phone to read it. That's why NFC cards never need charging and last for years.
What's stored on the chip?
Just a web link, stored in a standard format (NDEF) that phones recognise automatically. Business-card chips typically hold a few hundred bytes — plenty for a link, but nowhere near enough for photos or files. That's by design: the chip points to your online card, and the online card holds everything else.
On Cardly.ae, each chip is programmed with a short, unique Cardly.ae link that you control from your dashboard. You can point that link at a different card at any time — for example after a job change — without reprogramming the chip. If you lose a card, you can deactivate it so it no longer opens your profile. No personal data is stored on the chip itself.
Does it work with iPhone?
Yes. iPhones read NFC business cards without any app:
| iPhone model | How it reads NFC cards |
|---|---|
| iPhone XS, XS Max, XR and newer | Automatically, whenever the screen is on — tap the card near the top of the phone, then tap the notification that appears |
| iPhone 7, 8 and X | Add the NFC Tag Reader to Control Center (Settings → Control Center), open it, then hold the card near the top of the phone |
| iPhone 6 and older | Not supported — use the QR code instead |
The NFC antenna on an iPhone is at the top edge, near the camera. If nothing happens, make sure the screen is on, unlock the phone and try again. Background reading pauses while the camera or Apple Pay is in use and in airplane mode.
Does it work with Android?
Yes — most Android phones have supported NFC for years, and Android accounts for roughly 78% of UAE mobile page views. Two things to know:
- NFC must be switched on. It's usually on by default because it's also used for contactless payments. If not, look in Settings under Connected devices → Connection preferences → NFC (Google Pixel) or Connections → NFC and contactless payments (Samsung). Menus vary by brand; searching "NFC" in Settings finds it.
- The reading spot varies. On most Android phones it's around the centre or upper part of the back. Move the card slowly across the back until the phone vibrates.
When the phone reads the card, it usually opens the link in the browser straight away.
Where to tap: a quick guide
| Phone | Where to hold the card |
|---|---|
| iPhone | Top edge on the back, near the camera |
| Samsung Galaxy | Middle of the back |
| Google Pixel | Upper-middle of the back |
| Other Android phones | Middle or upper back — move slowly until it vibrates |
Keep the card flat against the phone and hold it for a second. You don't need to press hard.
What happens after the tap
- The phone reads the link and shows a notification (iPhone) or opens the browser (most Android phones).
- Your digital card opens: name, photo, contact buttons and links.
- The other person taps Save contact to add you to their phone, WhatsApp to message you, or shares their own details through your lead form.
On Cardly.ae, taps show up in your analytics as NFC visits, separate from QR scans and link clicks — so you can see how people found you.
Troubleshooting: when a card won't scan
- Screen off or locked? Wake and unlock the phone first.
- Wrong spot? Try the top edge (iPhone) or the middle of the back (Android).
- Thick or metal phone case? Cases with metal plates, magnets or card holders can block NFC. Try without the case.
- NFC switched off? On Android, turn it on in Settings.
- Older iPhone? Use the NFC Tag Reader in Control Center (iPhone 7–X) or scan the QR code.
- Metal NFC card? Some metal cards read best from one side or one end — try flipping it.
- Still nothing? Show your QR code instead. Every Cardly.ae card has one.
Always have a QR code as a backup
NFC is fast, but not every phone supports it, and some people prefer to scan. Your digital card's QR code opens exactly the same page. Keep it handy on your phone's lock screen or wallpaper, print it on brochures and booth banners, and add it to presentation slides.
Is NFC safe?
- The chip only shares a link. It can't read anything from the phone, access photos or install apps.
- The phone asks before opening. On iPhone, the user taps a notification to open the link.
- Range is tiny. A card has to be within a few centimetres of a phone to be read.
- You stay in control. On Cardly.ae you decide what your card shows, can re-point or deactivate a chip from your dashboard, and can protect your account with two-factor authentication.
When buying NFC cards from any seller, it's worth asking whether chips are locked after programming so nobody else can overwrite them.
