Use your card with NFC tap cards

NFC tags are the little chips inside "tap" business cards, stickers and keyrings. When someone holds their phone near one, your card opens — no app needed on their side.

1. Get a blank NFC tag

   Any NFC card, sticker or keyring marked NTAG213, NTAG215 or NTAG216 works. They're sold cheaply online and by most print shops.

2. Install a free NFC writer app

   For example NFC Tools (iPhone and Android).

3. Write your link

   In the app choose Write → Add a record → URL, enter https://qudo.ink/c/your-link, and hold the tag to the back of your phone.

4. Test it

   Tap the tag with another phone. Your card should open straight away.
