Age Verification
Prove age without exposing identity
CAIRL verifies a user's age using government-issued ID, then provides a reusable credential that partner sites can check — without ever seeing the document. One verification, used everywhere.
Features
Everything you need, nothing you don’t.
Privacy-First
The partner site never sees the ID. They get a yes/no answer to 'Is this person 21+?' and nothing else.
One-Time Verification
User verifies once with CAIRL, then uses that credential across every connected partner site.
Universal Acceptance
Works with driver's licenses, passports, and state IDs from all 50 US states.
Tamper-Proof
Verification credentials are cryptographically signed and tied to liveness checks — no sharing or spoofing.
How It Works
Upload ID
User takes a photo of their government-issued ID (front and back for driver's licenses).
Selfie Match
User takes a live selfie. CAIRL confirms the face matches the ID photo with 90%+ confidence.
Credential Issued
User receives a verified age credential stored in their CAIRL account.
Partner Verification
Partner sites check the credential via OAuth. They get age confirmation — never the document.
