NFC, QR or Link: Which One Works Where

NFC, QR and a plain link are usually presented as alternatives, as though a company picks one. They are not alternatives — they fail in different situations, and a digital card programme that offers only one has a predictable dead end. The useful question is which to reach for first and what happens when it does not work.

The comparison that matters

The fourth row applies to all three and is the one nobody plans for. None of these methods delivers a profile without a working connection — they all deliver a URL. In a hotel basement conference room, that is three methods failing at once for the same reason.

What each one is actually good for

NFC earns its place as an object, not as a transfer mechanism. Its real advantage over a QR code is that it is a physical thing you can leave on a desk, which preserves the social gesture a paper card provides. The tap itself is the least reliable part: whether it works depends on the handset, the OS version, whether NFC is enabled and where the antenna sits. Treat a successful tap as a pleasant outcome rather than the plan.

QR is the workhorse. Any phone with a camera can read one, it works across a table, and it works from a screen — which means it works in a video call, on a slide, in an email signature and on a conference badge. If you can offer only one method, this is the one.

The link is the fallback that always works. It costs nothing, it goes in a signature or a WhatsApp message, and it reaches people you never met in person — which is most of them. It is also the only method that works when the exchange is not face to face at all, and that is a larger share of business contact than the tap-focused marketing suggests.

One profile behind all three

The requirement that matters more than the choice: all three routes must resolve to the same profile, so a title change updates every one of them at once. If the NFC card holds its own copy of your details, you have reintroduced the exact problem the paper card had — a physical object carrying stale data — and you have paid more for it.

So the question to ask a vendor is whether the card stores a URL or a payload. A URL pointing at a profile you control is right. A vCard written onto the chip is a card that will one day be wrong and cannot be corrected without physically collecting it.

The order to use them in

In person, with a phone already out: QR, because it is the one that works. In person, wanting to leave something: hand over the NFC card and let the tap be a bonus — the card still has your name printed on it, so it functions as a paper card in the worst case. Not in person: the link.

And regardless of method, the profile should offer a way to save the contact properly on the recipient's phone. A share that ends with someone looking at a nicely designed page they will never find again has transferred nothing. The measure is whether your details are in their address book the next morning.
