WRITE AN NFC TAG · IN-APP
Write a tag without leaving ScanThis.
No NFC Tools install, no context switch. Android writes directly from the browser — hold a blank NTAG215 (or similar) tag against the phone and it's programmed. iPhone tag-writing is coming with the ScanThis app; for now, write from an Android phone.

ANDROID · CHROME 89+
Native, no app needed
The browser talks to your phone's NFC chip directly via the Web NFC API. Tap WRITE TO NFC TAG, hold a blank tag to the back of your phone.
IPHONE · IOS
Coming with the app
iOS doesn't expose NFC writing to the browser or to Shortcuts — only tag reading. Writing arrives with the ScanThis iOS app. Until then, write your tags from an Android phone.
DESKTOP
Open this on your phone
Writing happens phone-to-tag. Open this page on an Android phone (Chrome) and write the tag there.
