NFC card + link page

One card.
Every link.

Kadi is a card you tap on a phone, and a page that lives behind it. Your links, your socials, your numbers, your booking form — all of it, handed over in about a second. Nobody installs anything. Nobody types anything.

Tap it, or scan the QR on the back. Both go to the same place.

NFC card + link page

It is two things, and they belong together

One is plastic and lives in your pocket. The other is a web page you can rewrite at midnight. Neither is much use without the other.

The thing you hand over

A card with a chip in it

Credit-card size, printed on both sides, with an NFC chip sealed inside. The front is yours — a logo and a name, a photo, a job title, a full staff ID if that is what you need. The back carries a QR code drawn in your colours and the short code that ties the card to your account.

A page you actually own

Every card opens your own page on app.kadi.uno. Choose a theme from the library, add every link that matters — WhatsApp, Instagram, your menu, your shop, your phone number, your booking form — and drag them into the order you want. Change it as often as you like. The card in their pocket keeps working.

How it goes

Four steps, and only one of them is yours to do twice.

  1. Tell us what goes on the front

    A logo and a company name. Your face and your title. A full staff ID with a department and an employee number. Send us what you have and we will lay it out.

  2. We design it and print it

    We draw your QR code in colours that match the card — not a black square stuck in a corner — and print the whole thing, front and back.

  3. Tap once with your code

    The 4-digit code on the back is inside the QR too. Enter it once and the card is bound to your account. That is the only time you will ever need it.

  4. Edit your page forever

    New job, new number, new campaign, new song. Update the page. Every card ever printed points at the new version the moment you save.

The card

What is actually printed on it

Nothing hidden, nothing decorative that is not doing a job.

  • Your name and what you do

Back

  • Your QR code, drawn in your own colours
  • Your 4-digit activation code, printed and encoded
  • The address of your page on app.kadi.uno
  • Nothing else. It is a back, not a billboard.

If their phone cannot do NFC, the QR still can

This is the part people worry about, so here it is plainly. Most phones made in the last several years read NFC tags by holding them near the top of the handset — no app, no setting to find. If a phone is older, or NFC is switched off, or somebody is just not sure, they point the camera at the QR code on the back instead. Same page, same second, no explaining.

Tap

Hold the card near the top of the phone. The link appears as a notification.

Or scan

Open the camera, point it at the back of the card, tap the banner.

Or type

The address is printed on the card. Worst case, it can be read out loud.

Who it is for

Anyone who has ever spelled out a username across a noisy room.

People who meet people

Sales, consulting, property, insurance, recruitment. One card replaces a stack of paper that is out of date the day it is printed.

Places customers walk into

A restaurant, a salon, a clinic, a boutique. Leave it at the counter and let people take away the menu, the booking link and the socials.

Teams and companies

Print the whole staff at once. Same card design, each one bound to its own page, each employee editing only their own.

Anyone with an audience

Musicians, creators, coaches, churches. Every link you have ever put in a bio, on one card you can hand to a stranger.

Your page

The page behind the card

Built on LinkStack, which we host for you, so there is nothing for you to run.

Themes

Pick from the theme library and switch whenever the mood changes. Your card does not care.

As many links as you want

Socials, phone, WhatsApp, email, maps, menu, shop, booking, a PDF. Add, remove, reorder.

Yours to edit

You sign in, you make the change, it is live. No ticket to raise, nobody to wait for.

One address

Your page sits at app.kadi.uno and it does not move.

The questions everybody asks

Does this work on my phone?
Almost certainly, in one way or the other. Most phones made in recent years read NFC tags by holding the card near the top of the handset, with no app and no setting to hunt for. If a phone will not tap — an older model, NFC switched off, or a locked-down work device — the QR code on the back does the identical job through the camera. That is why every card has both.
Does the person I hand it to need an app?
No. Nothing to install, nothing to sign up for, no account. They tap or they scan, a web page opens, and that is the whole interaction.
What is the 4-digit code for?
It binds a printed card to your account, once. Cards are printed before they belong to anyone, so the code is what turns a blank one into yours. Enter it the first time you tap your own card and then forget it — it is never needed again.
Can I change my links after the card is printed?
That is the entire point. The card carries a pointer, not a copy. Change your page as often as you want and every card you have ever handed out follows along the moment you save. Nothing you have printed ever goes out of date.
What if I lose the card?
Tell us and we will sort out a replacement. Your page and your links are on your account, not on the card, so nothing you built is lost with it.
