Credential expiration reminder systems use calendar alerts, email/SMS notifications, or in-app prompts to warn users of upcoming expirations. Dashboards visualize credential lifecycles, highlighting near-expiry items. Automated workflows trigger renewal requests via verifiable credentials (VCs) or integrate with issuers for seamless updates. Blockchain-based systems use smart contracts to send decentralized notifications, while AI predicts expiration risks based on usage patterns, ensuring compliance without manual oversight.
