What is an NFC business card?

A physical card or tag with an NFC chip inside. Tapped against a phone, it opens a web page — the chip stores an address, the page carries your details. You buy the chip once; the page does the ongoing work.

Does Pubtact sell NFC cards?

No. Pubtact is the page your tap opens. Buy any writable NFC card or tag you like — or reuse one you already have — and write your page's URL to it.

Which phones can read the tap?

Most recent iPhones and Android phones read an NFC tag out of the box, no app needed. For everything else, the same page is one QR scan away.

What happens when my details change?

Nothing happens to the tag, and that is the point. It stores your page's address, not your details. Edit the page; every tap from then on opens the current version.

How do I write my URL to a tag?

Any free NFC-writing app on a modern phone can write a URL to a writable tag in a few seconds. Write once, share forever.

NFC business card

The NFC business card where the hardware stays yours.

An NFC business card is two things: a tag that wakes a phone, and the page that opens next. Pubtact is the second half — a contact page worth landing on — and it works with any writable tag, so the tap is hardware and the card is a page.

Free to start, no card needed. Your page is live the moment you publish it.

Why it works

The page half of an NFC business card.

Bring any tag

Write your Pubtact URL to any compatible NFC card, sticker or ring. No vendor-specific hardware required.

No lock-in on the tap

The tag stores an address; the page behind it stays yours to edit. Replace the tag anytime without reprinting anything.

One tap to save

The page opens on their phone with your details ready to save to contacts.

QR as the fallback

Phones that miss the tap scan the same page's QR — nobody leaves without your details.

At a glance

Which NFC tag to buy — the thirty-second version.

Chip	Usable memory	Fits a Pubtact URL?	When it makes sense
NTAG213	~144 bytes	Yes, comfortably — a short handle URL is well under it	The default. Cheapest, everywhere, enough
NTAG215	~504 bytes	Yes	Only if you also want other records on the same tag
NTAG216	~888 bytes	Yes	Overkill for a URL; pay for it only if repurposing

Buy blank, writable, non-locked tags from any electronics seller. A URL this short never needs the bigger chip — vendors upsell capacity the job cannot use.

How it works

Three steps, no app.

Publish your card

Claim a handle and build the contact page the tap will open.

Write the URL to a tag

Any free NFC-writing app copies your page's address onto a writable tag in seconds.

Tap, open, save

The receiver's phone opens your page; one tap saves your details.

Straight answer

The parts of this we do not control.

We sell no tags and cannot write one for you — you buy a blank NTAG213 or similar and write the URL yourself with a free app. Taps also fail on phones with NFC switched off, on iPhones older than the XR, and on any tag that shipped locked. Print the QR as the fallback rather than trusting the chip alone.
