Palm Verification SDK

The VeryAI Palm Verification SDK adds palm biometric enrollment and verification to your iOS and Android app. Users scan their palm using the device camera, and the SDK returns a signed proof of identity to your app.

What you get

• On-device palm capture — guided camera UI, no WebViews or browser redirects
• Enrollment + verification — register new users and verify returning users
• Signed identity proof — Ed25519-signed JWT token your backend can verify
• Fraud screening — AI-powered quality review flags tampered or fake palms

How it works

1. Register your app in the Developer Portal and get an SDK API key
2. Configure the SDK with your sdkKey and optional userId
3. Call authenticate() - the SDK opens the camera and guides the user through a palm scan
4. On success, the SDK returns a VeryResult with userId and signedToken
5. Your backend verifies signedToken with VeryAI's JWKS endpoint
6. Trust the verified JWT sub claim as the user's VeryAI ID

Palm Verification SDK integrations do not require an OAuth client_id or client_secret. Use OAuth credentials only for a separate browser-based "Sign in with VeryAI" flow.
