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. iPhone runs a one-tap Shortcut you add once. Hold a blank NTAG215 (or similar) tag against your phone and it's programmed.

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 13+
One-tap Shortcut
iOS doesn't expose NFC writing to the browser. Our Shortcut closes the gap — install once via iCloud link, then run it from the Shortcuts app or home screen.

Writing happens phone-to-tag. Send this page to your phone (the URL bar QR works) and write the tag there.
