Credential expiration reminder systems track VC validity periods via blockchain timestamps and smart contract alerts. Users receive push notifications, emails, or SMS reminders before expiry (e.g., "Driver’s license expires in 30 days"). Dashboards display upcoming renewals, while automated workflows trigger reissuance requests to issuers. APIs integrate with calendar apps for proactive scheduling. Compliance tools ensure reminders align with regulatory deadlines (e.g., GDPR, HIPAA).
