The NFC Writer module lets you encode node URLs directly onto NTAG213/215/216 chips from the NearNode console — no third-party apps required.

​
Supported Methods

Web NFC (Mobile)

Use your Android phone’s built-in NFC to write tags. Works in Chrome and as an installed PWA.

Desktop Reader

Connect an ACR1252U USB reader for batch writing workflows. Coming soon.

​
Web NFC Quick Start

1

Open the Writer

Navigate to Writer in the NearNode dashboard on your Android phone (Chrome or installed PWA).
2

Select a Node

Choose the node you want to write. The URL nearnode.io/v/{slug} will be encoded as an NDEF URL record.
3

Tap to Write

Hold the NFC tag to the back of your phone. The writer will encode the URL and optionally verify the write.
4

Lock (Optional)

Enable “Lock after write” to make the tag permanently read-only. This is irreversible.
Locking a tag is permanent and irreversible. The chip can never be re-written after locking. Only lock tags when you’re certain the correct URL has been written.

​
Offline Support

The NearNode PWA supports offline writes. When you’re offline:
  1. Tags are written normally via Web NFC
  2. Write logs are queued in IndexedDB
  3. Logs sync automatically when you’re back online
Install NearNode as a PWA for the best writing experience — standalone mode, no browser chrome, and offline queue support.

​
Write Log

Every write creates an immutable audit record with: Write logs cannot be edited or deleted — they serve as a tamper-proof audit trail.
