✍️ Program a card

Write a tap-to-open link onto an NFC card. After this, tapping the card on any phone opens the log page with the card already filled in — no app needed.

iPhone (or no Web NFC)?

Writing from the browser works on Android Chrome only. On iPhone, use the free NFC Tools app: choose Write → Add a record → URL/URI, paste the URL shown above, then Write and hold the card to the top of the phone. Reading the card afterward works on both iPhone and Android with no app.
