How to Program the NFC Tag in Your NerdMatter3D Smart Business Card

Welcome to your new NFC business card, custom-made by NerdMatter3D.

Whether you ordered one of our minimalist personal cards or a custom branded business card for your company or team, the setup process is quick, simple, and completely customizable.

Every card includes a rewritable NFC (Near Field Communication) chip that lets you instantly share your most important link with a single tap of a smartphone.

This guide walks you through how to set up your card in under a minute.


What Your NFC Card Can Do

Your NFC card can be programmed to open any link you choose, including:

  • Linktree or AllMyLinks
  • Instagram, TikTok, YouTube
  • Etsy storefront
  • Personal website or business homepage
  • Online portfolio or resume
  • Digital business card page
  • Menu or booking system
  • vCard/contact file
  • Payment links
  • Any URL you want to share

You’re free to rewrite the NFC tag whenever you want. Tags are not locked unless you choose to lock them yourself.

How to Program Your NFC Business Card

This process applies to all of our NFC cards, whether personal or company-branded.
You’ll need a free app called NFC Tools, available on both iPhone and Android.


Programming on iPhone

  1. Download NFC Tools from the App Store
  2. Open the app
  3. Tap Write
  4. Tap Add a record
  5. Choose URL
  6. Enter the link you want the card to open
  7. Tap OK
  8. Tap Write
  9. Hold the top edge of your iPhone to the card

Once the app confirms the write, your card is ready.


Programming on Android

  1. Download NFC Tools from Google Play
  2. Open the app
  3. Tap Write
  4. Tap Add a record
  5. Choose URL
  6. Enter your link
  7. Tap OK
  8. Tap Write
  9. Hold the back of your phone to the card

Android usually writes almost instantly.


Changing Your Link Later

Yes, you can update your card anytime.
Your NFC chip is fully rewritable, so you can change your link as often as you like using the same steps above.


Are NFC Tags Locked?

No, we do not lock any NFC tags by default.

Unlocked tags allow you to:

  • update your link later
  • change your business info
  • reuse the card for a new job or new project
  • temporarily redirect links
  • switch between personal and business links

Locking a tag in the app is permanent, so we recommend leaving it unlocked unless you have a specific reason.


Troubleshooting and Tips

If the card isn’t reading:

  • Tap the top edge of the iPhone
  • Tap the back center of most Android phones
  • Make sure NFC is turned on (Android)

If it only works inside the app:

  • The device is likely an older iPhone model (7, 8, or X) that requires app-based reading

If the card won’t store a file:

  • NFC tags hold very small amounts of data
  • Always store a URL rather than a file

If multiple people share one card:

  • Yes, this works fine
  • Many teams use branded cards with individual or shared links

You’re Ready to Use Your NFC Card

Whether you're using a minimalist personal card or a fully branded company card, your NFC business card is now ready to share your digital identity with a tap.

If you want a pre-programmed card, a custom link, or a fully branded batch for your business or event, we’re happy to help.
