# Self Pass

Privacy-preserving identity verification using zero-knowledge proofs.

## Overview

Self Pass enables developers to verify real-world identity attributes without exposing personal data. Users scan their passport, national ID, Aadhaar card, or KYC attestation with the Self app, which generates a zero-knowledge proof on-device. Applications can then verify specific attributes (age, nationality, sanctions status) without ever seeing the underlying document.

## Supported Documents

* **Passports** — NFC-enabled passports from 60+ countries
* **EU National ID Cards** — Chip-enabled European identity cards
* **Aadhaar** — India's national identity system
* **KYC Attestations** — Third-party KYC provider attestations

## Getting Started

Start with the [Quickstart](quickstart.md) guide, or fork the [boilerplate repo](https://github.com/selfxyz/self-integration-boilerplate) for a working example.

## Integration Options

| Path | Description | Guide |
|------|-------------|-------|
| **Frontend SDK** | Display QR codes to request proofs from users | [QRCode SDK](frontend/qrcode-sdk.md) |
| **Backend SDK** | Verify proofs server-side on a Node.js backend | [Backend Integration](backend/basic-integration.md) |
| **Smart Contracts** | Verify proofs on-chain in a trustless manner | [Contract Integration](contracts/basic-integration.md) |
| **Mobile SDK** | Embed Self verification directly in a React Native app | [Mobile SDK](mobile-sdk/getting-started.md) |
