Membership Cards for the Digital Age
Issue verifiable memberships. Members prove status anywhere. Auto-expire on lapse. No more "is this card still valid?" calls.

Frequently Asked Questions
Members present their verifiable credential (QR code or wallet pass). The partner scans and verifies membership tier in real-time. Discount applied automatically — no manual lookup needed.
The credential automatically stops verifying after the membership period ends. No manual revocation. If they renew late, you issue a new credential.
Yes. Conference registration scans their membership credential and applies member pricing. No 'show your card' — cryptographic proof of current membership.
Tiers are claims in the credential (Gold, Silver, Fellow, etc.). Verifiers see the tier and apply appropriate benefits. Upgrade? Issue a new credential with the new tier.
Each family member gets their own credential linked to the primary membership. Revoke the primary and all linked credentials stop verifying.
