Kayle ID produces an identity-assurance signal by reading the cryptographic chip in an identity document, matching the on-chip portrait against a live selfie, and returning only the claims you asked for. The end user keeps custody of their document data; you receive the Kayle check result and the fields the user consented to share. You remain responsible for any access, onboarding, eligibility, or account decision you make from that signal. ## Start here Create your first verification session in about ten minutes.
