# NFC vs QR for Business Cards: Which Actually Works

> NFC tags and QR codes solve the same problem differently. What each one needs from the other person, where each fails, and why we sell neither.

## Short answer

**QR wins at distance and on any screen; NFC wins when you want a physical object to feel like a product.** The deciding question is not which technology is newer. It is whether the other person can physically reach the thing you are holding. Cardr sells neither, which is why this comparison is not trying to talk you into hardware.

## What each one asks of the other person.

This is the whole comparison. Everything else is detail.

**NFC** needs their phone within a couple of centimetres of the tag. That means they have to take their phone out, unlock it, and physically touch it to the card or the tag in your hand. It is a genuinely nice moment when it works, and it works about as well as the other person’s willingness to hold their phone against a stranger’s object.

**QR** needs them to point a camera at a shape. That works from across a table, across a desk, from a screen, from a printed page, or from a lanyard while both of you are holding drinks. It also works when they are already holding their phone, which is most of the time.

Drawn to one scale, the difference stops being a matter of opinion.

**NFC** Up to 4cm

They unlock their phone and touch it to the thing in your hand. There is no version of this that happens across a table.

**QR** About 10× the code’s width

A 5cm code on a phone screen reads from about half a metre. A 20cm code on a stand reads from about two, which is why the bar fades rather than stopping.

Distance from the code

**0**

**50cm**

**100cm**

**150cm**

**200cm**

Drawn to one scale. NFC's specified operating range is up to 4cm, which is 2% of the width of this figure. A QR code reads from roughly ten times its own width, so the far end of that bar moves with how big you print it — which is why it fades rather than stopping.

There is a second asymmetry that gets skipped. Background NFC tag reading has been standard on iPhones since the XR and XS (Apple’s Core NFC documentation says “iPhone XS and later”), but on the iPhone 7, 8 and X the reader has to be opened from Control Center first, and most people do not know it is there. QR scanning has been in the native iPhone camera since iOS 11 and in effectively every Android camera app for as long.

## Side by side, including the third option.

Most comparisons give you two columns. The one people actually end up running has three.

NFC, QR and the setup most people actually end up with

|   | NFC tag | QR code | Printed card with a QR on it |
| --- | --- | --- | --- |
| What it needs from them | Phone out, unlocked, and touched to the tag | A camera pointed at a shape | A camera pointed at a shape |
| Works across a table | No | Yes | Yes |
| Works when your phone is dead | Yes | No | Yes |
| You can leave it behind | Only by giving the card away | No | Yes |
| Details can change later | If the tag points at a URL | If the code points at a URL | If the code points at a URL |
| Lets them send you their details | No | Only if the page asks for them | Only if the page asks for them |
| What it costs you | Per card, from a printer | Nothing | Per card, from a printer |

Cardr sells neither the tags nor the printing, which is why this table has no column for us in it.

## What both of them get wrong.

The tap is not the problem. Nobody has ever lost a deal because a tap was slightly slow.

Both technologies solve getting your details onto their phone. Neither solves the thing that actually decides whether the conversation turns into anything: **you leaving with their details, and a reason to write.**

An NFC card that dumps your contact into their phone gives you nothing back. A QR code that opens your web page gives you nothing back. In both cases you have handed over information and received none, and a week later you have no record that the conversation happened.

That is the argument for an exchange rather than a broadcast, and it is the reason Cardr’s free tier includes the return leg rather than charging for it. Whichever way the details travel, the useful part is what comes back. [The follow-up is where that gets spent.](https://cardr.co/blog/how-to-follow-up-after-networking)

## So which should you buy.

Including the case where the answer is not us.

Cardr does not sell hardware, so there is nothing here we need you to pick.

Four situations. The honest answer is us in one of them.

- You already own NFC cards → **Keep using them**. Point the tag at your card’s web address and it works exactly as before. Nothing to replace.
- You are deciding from scratch → **Start with QR**. It costs nothing, works at any distance and cannot run out. Add tags later if you find you want the object.
- What you want is a physical object → **[Buy printed cards](https://cardr.co/blog/are-paper-business-cards-dead)**. Not an outdated choice, a different one. Put a code on them and you have both.
- You want to leave with their details too → **[That is the exchange](https://cardr.co/)**. Neither a tag nor a code does the return leg. Ours is free, including the part that comes back.

## Questions, answered

### Do NFC business cards work on every phone?

Not equally. Background tag reading is standard on recent iPhones and on most modern Android handsets, but older iPhones need the NFC reader opened from Control Center first, which most people do not know about. QR scanning works from the native camera on effectively everything.

### Does Cardr sell NFC cards?

No. Cardr’s one physical product, Cardr Metal, is a metal business card with a QR on the back, for the reasons on this page. If you have NFC cards from a printer, point the tag at your cardr.co address and they will open your card.

### How far away does a QR code scan from?

The working rule is about ten times the code's own width. A 5cm code on a phone screen reads from roughly half a metre; a 20cm code on an exhibition stand reads from roughly two. NFC, by contrast, is specified to work only within about 4cm.

### Can one card have both?

Yes, and it is the common setup. A printed card with a QR code on it, and an NFC tag inside it, both pointing at the same web address. The address is the thing that matters; the tag and the code are just two ways of reaching it.

### Is a QR code less professional?

That is a taste question and it has moved a lot. QR went from novelty to completely ordinary during the years restaurants used it for menus. In most rooms in 2026 nobody thinks about it. In some rooms a heavy printed card still signals more, which is a real thing and not a technology problem.
