Any NFC tag. Your card. About fifty cents.

Smart-card companies charge $20–35 for a piece of plastic. You don't need it. Any blank NFC tag works — here's how.

What you need

  • A blank NFC tag — NTAG213, 215, or 216 (the common, cheap kind, ≈ $0.50 each in multipacks). Browse NTAG215 NFC tags on Amazon.
  • A smartphone with NFC — most modern Android phones, or iPhone XS and newer.
  • A free NFC writer app — e.g. NFC Tools, NXP TagWriter, or Simply NFC (all free on iOS and Android).

Six steps, about two minutes

  1. 01

    Get your vcardonce card link

    Copy your card URL from the vcardonce dashboard (e.g. vcardonce.com/c/yourname).

  2. 02

    Install a free NFC writer app

    On iOS or Android, install a free NFC writer app such as NFC Tools, NXP TagWriter, or Simply NFC.

  3. 03

    Choose Write → Add a record → URL/URI

    Open the app and start a new write action. Select the URL/URI record type.

  4. 04

    Paste your vcardonce card link

    Paste the link you copied from your dashboard into the URL field.

  5. 05

    Hold the blank tag to your phone and tap Write

    Place the NFC tag against the back of your phone and tap Write. It takes about a second.

  6. 06

    Test it

    Tap the tag with your own phone. Your vcardonce profile should open instantly.

Which tag should I buy?

NTAG215 is the sweet spot — enough memory for a URL plus future-proofing, and the most widely compatible chip.

  • Round 25 mm stickers — stick on the back of a phone case, a laptop lid, a notebook, or your shop counter.
  • PVC card format (85.5 × 54 mm) — looks like a real business card, double-sided printable, slides into a wallet.

Why we don't sell you one

We could ship you a $30 card. But a blank tag costs cents, you can re-write it anytime, and you're not locked into us. That's the whole point of vcardonce — you own it.
