iOS + Android Native NFC

Bulk write tags.
Sync events. Keep history.

NFC Memo is built for teams deploying many tags fast. Write in continuous bulk sessions, send read/write events to your backend, and keep a reliable write history for audits and support.

Value

Three features that deliver real operational value

If you care about speed, integration, and accountability, these are the parts of NFC Memo that matter.

⚡

Bulk Write

Write many tags in one session with per-tag verification and optional password protection after each write.

🔗

Webhook

Send read/write events to your server in real time so your team can automate tracking and downstream actions.

📋

History

Keep a searchable log of writes with UID, payload, and timestamp to resolve issues and verify operations.

Bulk Mode

Bulk write without repeating the same setup

Enter content one time, start bulk mode, then tap tags continuously. NFC Memo verifies each successful write as you go.

Use ### in URLs to inject each tag's UID automatically during batch runs.

Optional lock-after-write helps prevent unauthorized overwrites when tags are deployed in the field.

Webhook

Webhook quickstart for read/write automation

Set one endpoint URL, enable webhook toggle in-app, and NFC Memo will POST structured JSON on every successful read or write.

What it solves: connect NFC activity to your backend instantly for tracking, alerts, or workflows.

When it fires: every successful read and write operation where webhook toggle is enabled.

Safe behavior: webhook failures do not block NFC operations in the app.

Set endpoint in Settings

Open Settings in the app and paste your webhook URL (must accept JSON POST).

Enable toggle on Read/Write tab

On the tab where you need automation, switch on Send to webhook.

Scan or write a tag

Check your server logs and confirm a payload arrives with tagId, type, content, and timestamp.

Payload sent by NFC Memo

{
  "tagId":     "04:A3:2B:1A:7C:E1:04",

  "content":   "https://example.com",
  "timestamp": 1711036800000    // Unix ms
}

Payload fields (meaning)
tagId: unique NFC tag serial number (UID).
type: url, contact, or read.

Minimal Node.js receiver

// npm i express
const express = require('express');
const app = express();
app.use(express.json());

app.post('/webhook', (req, res) => {
  console.log(req.body);
  res.sendStatus(200);
});

app.listen(3000, () => console.log('Webhook server on :3000'));
