Server-side processing

How It Works

Four simple steps from document scan to verified data — all processing stays server-side.

Step 1

Scan MRZ

User scans the Machine Readable Zone on their passport or ID card using the mobile app camera.

Step 2

Tap NFC

The app connects to the document's NFC chip and opens a relay channel to the KZ-ID server.

Step 3

Server Processes

All chip authentication and data extraction runs entirely on our server — nothing sensitive ever touches the client.

Step 4

Data Returned

Verified identity data (name, DOB, photo, nationality) is returned via your API integration.

Developer Preview

Built for Developers

A clean API that abstracts away all complexity. You send MRZ and relay NFC — we handle the rest.

verify.ts
// 1. Start a verification session
const session = await fetch("https://api.kz-id.com/v1/sessions", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    mrz: "P<UTOERIKSSON<<ANNA<MARIA...",
  }),
});

// 2. Connect via WebSocket for NFC relay
const ws = new WebSocket(session.wsUrl);
ws.onmessage = (msg) => {
  // Forward command to NFC chip, send response back
  const cmd = JSON.parse(msg.data);
  const response = await nfc.transceive(cmd.command);
  ws.send(JSON.stringify({ response }));
};

// 3. Receive verified data
ws.on("verified", (data) => {
  console.log(data.name, data.dateOfBirth, data.photo);
});

REST + WebSocket

REST to create sessions, WebSocket for real-time NFC relay.
