Direct Tag Writing (Web NFC)
Web NFC Compatibility Notice
Direct in-browser NFC writing is currently restricted by browser operating systems. It is supported on Google Chrome for Android (v89+) with NFC hardware enabled.
Desktop browsers, iOS Safari, and Firefox do not expose the Web NFC API. You can still export the .NDEF binary payload or copy the formatted text above to flash tags with NFC Tools on iOS or macOS.
NFC URI Record Architecture & Smart Tap Best Practices
Optimized for NTAG213, NTAG215, and NTAG216 contactless RFID microchips.
Instant Tap-to-Launch
Launches mobile browsers natively without requiring special scanning applications.
Compact NDEF URI Record
Standard RFC 3986 URI prefixes (https://) are optimized for minimal byte consumption on small NTAG213 chips.
In-Browser Web NFC Flashing
Flash smart stickers and badges immediately on Android Chrome devices with zero software downloads.
Frequently Asked Questions
Clear technical answers to help you design, test, and deploy with confidence.
Do iPhones and Android phones need an app to open an NFC web link?
No. All modern smartphones (iPhone XS and newer, plus virtually all modern Android phones) feature background NFC tag reading. Tapping an NFC tag encoded with a standard URL immediately pops up a banner asking to open Safari or Chrome.
How much data can an NFC tag hold for a URL?
An NTAG213 chip holds up to 144 bytes, which is plenty of space for a 130-character URL. For longer URLs with UTM tracking parameters, use an NTAG215 (504 bytes) or NTAG216 (888 bytes).
Can I lock an NFC tag after programming the URL?
Yes. Most NFC chips support permanent write-locking (setting the lock bytes), preventing anyone from overwriting your link in public venues or retail stores.
