A globally interoperable micro-credential is a digital credential designed to be issued, stored, shared, and verified across different technical platforms and regional (including cross-national) credentialing systems.  Interoperability is achieved by aligning credential data models and cryptographic verification methods (codes that keep information secret) with multiple recognized standards so that credentials are not locked into a single proprietary ecosystem.

These micro-credentials address a persistent challenge in the ecosystem: credentials that cannot travel across institutions, digital platforms, or national systems. Emerging implementations such as the Velocert Globally Interoperable Micro-credentials illustrate how technical and regulatory standards can be combined to improve portability, trust, and long-term verifiability of learning achievements. The Velocert micro-credential supports simultaneous issuance in Open Badges v3 and European Digital Credentials for Learning (EDC) formats. This approach enables a single credential to remain verifiable in both global badge-based systems and in European digital credential and wallet infrastructures.

Characteristics of these micro-credentials:

• Standards-aligned — Support multiple credential standards to enable cross-platform portability
• Machine-readable and verifiable — Use cryptographic methopds to ensure authenticity and detect tampering
• Learner-controlled — Designed for storage in digital credential wallets where individuals manage sharing
• Cross-border recognition — Align with European and international credential frameworks
• Metadata-rich — Can include learning outcomes, workload, assessment criteria, and skill taxonomies
