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 Standards, NDEF Formats & Hardware Specs
Adheres strictly to NFC Forum Type 2/4/5 specifications for universal tap compatibility.
7 Core NDEF Record Types
Generate compliant payloads for URLs, text memos, digital vCards, direct phone calls, email drafts, Wi-Fi configs, and map locations.
Direct Web NFC Tag Writing
Program physical NFC tags directly in Google Chrome on Android with native hardware integration.
Live NDEF Byte Inspector
Inspect total byte footprint, record header structures, and full hexadecimal byte streams in real time.
Binary & JSON Export
Export raw .NDEF binary streams and JSON profiles compatible with industrial NFC flashing machines and mobile programmer apps.
No External App Required
Properly programmed URL records launch automatically in mobile web browsers on both modern iPhones and Android devices.
Zero Data Logging
All payload formatting and Web NFC transmissions run locally inside your browser session for maximum privacy.
Frequently Asked Questions
Clear technical answers to help you design, test, and deploy with confidence.
What is an NFC tag and NDEF format?
NFC (Near Field Communication) tags are small, passive semiconductor chips with an embedded antenna. NDEF (NFC Data Exchange Format) is the standardized data structure established by the NFC Forum that allows smartphones to parse URLs, contact business cards, and Wi-Fi credentials on tap without opening an app.
Can I write NFC tags directly from this web page?
Yes, if you are using Google Chrome on an Android smartphone with NFC hardware enabled, the Web NFC API allows this website to program physical tags (NTAG213, NTAG215, NTAG216) with a single tap. On desktop or iOS, you can download the .NDEF binary payload or copy the formatted text into mobile tools like NFC Tools.
Which NFC chip types are compatible?
Standard NDEF payloads generated here work with all Type 2, Type 4, and Type 5 NFC Forum chips, including the widely popular NTAG213 (144 bytes), NTAG215 (504 bytes), and NTAG216 (888 bytes).
Do NFC tags require a battery?
No. Passive NFC tags require no internal battery. When an NFC-enabled smartphone comes within 1–4 centimeters, the phone's electromagnetic field powers the chip via inductive coupling to read the stored payload.
