## How it works
Use IDKit to integrate Selfie Check into your application.
-* **On mobile (iOS/Android):** Use IDKit to generate a deep link and attach it to a "Verify" CTA. When the user taps it, they are redirected to World App to complete Selfie Check.
-* **On desktop:** Use IDKit to generate a QR code and display it to the user. When the user scans it with their mobile device camera, World App launches and guides them through Selfie Check.

## How it works
-Send a **proof request** through IDKit, challenging the user to prove something about themselves — such as uniqueness, document possession, or liveness — based on their [credentials](/world-id/overview#credentials). The user's World ID app generates a zero-knowledge proof without revealing personal data. Your backend then verifies the proof and stores a **nullifier** (a per-app, per-action identifier) to prevent the same person from verifying twice.
