Program an NFC business card

Install a writing app, write your public Zapped URL, test the NFC card, and lock it only when ready.

An NFC business card can open your public vCard when someone taps it with a compatible phone. This guide covers the complete setup, from choosing a writable tag and installing an app to testing the tap and updating the profile later.

Before you start

Set up your writing kit

Get the public Zapped link, a writable NFC card, and a device that can write NFC. Then choose the setup that matches the device in your hand.

Public Zapped URL

Open the card in Zapped, copy its public URL, and open it in a browser once before writing it to a chip.

Writable NFC card

Use an unlocked NFC card or tag. NTAG213, NTAG215, and NTAG216 are common options for a web link.

NFC switched on

Enable NFC in your phone settings when your device requires it. Remove a thick case before writing or testing.

Keep it editable

Do not lock the chip yet. A locked tag cannot be rewritten if you later change the destination URL.

Choose your writer

Install the right app for your device

Use a phone for the simplest setup. A USB reader is optional when you need to program cards from a computer.

iPhone

Write from your iPhone

Install NFC Tools, then use Write, Add a record, and URL / URI. Keep the card near the top of the phone until the app confirms the write.

Open NFC Tools for iPhone
Android

Write from your Android phone

Install NFC Tools, then use Write, Add a record, and URL / URI. Hold the card against the back of the phone until the app confirms the write.

Open NFC Tools for Android
PC or Mac

Use a USB NFC reader

This route is optional. Use NFC Tools for PC or Mac only when you already have a compatible USB NFC reader and want to program cards from a computer.

Open NFC Tools for PC or Mac

Prepare, write, and test the NFC card

  1. Open the card from Cards and copy its public URL.
  2. Open the writing app, choose Write, then choose Add a record or URL / URI. The exact label can vary by app version.
  3. Paste the public Zapped URL, save the URL record, and choose Write. Hold the NFC card flat against the phone until the app confirms the write. Keep the phone still during the transfer.
  4. Use the app’s Read function to scan the tag again. Confirm that it shows the expected URL, the tag is writable, and the record is an NDEF URL record.
  5. Tap the card with an iPhone and an Android phone. Confirm that both open the expected public profile, the profile loads over HTTPS, and the important contact actions work.
  6. Lock the chip only after every test passes and you are sure the destination URL will not change. A locked chip cannot be rewritten.
  7. Update the profile in Zapped whenever needed. If the public URL stays the same, those content changes appear on the next tap without rewriting the chip.

Good ways to use this

  • Write the public card URL, not the editor URL or Dashboard URL.
  • Use an NTAG-compatible writable card and keep it unlocked until testing is complete.
  • Test the NFC card with both an iPhone and an Android phone after programming it.
  • Keep a QR code fallback on printed materials for phones that do not read NFC reliably.

Common questions

Can I update the card after programming NFC?

Yes. If the NFC card points to the same public URL, content changes in Zapped appear when that URL opens. You only need to rewrite the chip if the destination URL changes.

How do I reprogram an existing NFC card?

Read the tag first and confirm it is writable. In NFC Tools, use Other to erase or overwrite the existing URL record, then return to Write, choose Add a record and URL / URI, paste the new URL, write it, and read it back. Do not try to reprogram a locked tag.

Can one NFC card open multiple profiles?

An NFC card opens one saved destination at a time. Reprogram it if you need it to open a different card.

Should I lock the NFC chip?

Only lock it after you have tested the destination on the phones your audience will use. A locked chip cannot be rewritten.

If something looks wrong

  • If the tap does not work, confirm NFC is enabled on the phone, remove a thick case, and test with a known working NFC reader app.
  • If the wrong profile opens, rewrite the NFC card with the correct public card URL.
  • If the chip cannot be rewritten, check whether it was locked during an earlier test.
