Share your digital card with an NFC tap

How an NFC business card works

The card or tag stores a link read near the NFC reader of a compatible phone. Opening that link displays your public page. It does not automatically save a contact: the recipient chooses Save Contact and confirms the import.

What you need

1. A completed ETA Card page available for public viewing.
2. A physical NFC card or tag that can store a web URL, or an issued ETA card linked through the account activation process.
3. A recipient phone that supports the tag, with reading enabled when needed and connectivity to open the page.

Link and test your card

For a writable tag, use a compatible writing tool to store only your public page URL, then test it. For an issued ETA card, follow the activation flow in your account. Never write the secret activation code to the tag or put it in a public URL.

Update your details while keeping the URL

When the tag opens the same ETA Card page URL, changing page details does not require rewriting the tag. A changed destination or disabled linked card needs a configuration review. Test a writable tag before permanently locking it.

Keep QR as another option

Print a QR for the page on your card or display it on your phone. This helps when a recipient lacks NFC support or cannot locate the reader. Test both methods on different devices before an important event.

A digital page and physical hardware

Free includes the digital page, links and QR. Creating an account does not order or ship a physical NFC card. Contact support@eta-int.com about physical card availability and activation.
