Use Cases

Use cases for VIABLE.

Interactive demos that verify identities and orchestrate credentials, cutting manual checks across mobility and hospitality.

Continuing Education · Verifiable Skills

Training credential issued. Skill verified. Zero transcript overshare.

A learner receives a Certified ML Engineer Credential from Meridian University. Months later, they apply to a new role and prove they're certified, without disclosing grades, thesis topic, or internal student ID.

When inspection has to happen without network coverage, traditional verification fails. VIABLE verifies anywhere, fully offline, zero metadata leakage.

Zero-Connectivity · Edge

No signal. No server. Still verified.

Underground in the U2 tunnel between Ernst-Reuter-Platz and Zoologischer Garten, both the passenger's wallet and the inspector's terminal lose connectivity. The verification still happens: locally cached keys, locally synced revocation registry, NFC tap. Zero backend calls.

Cross-organisational workflows usually depend on central brokers and bespoke integrations. VIABLE replaces them with a composable, auditable process engine any organisation can run.

Universal Execution Engine

From BPMN to the Edge, in one airdrop.

Compile your business processes once. Inject them into any VIABLE Wallet via QR or NFC. The wallet itself executes the logic, verifying credentials, transitioning states, triggering actions, entirely offline, with zero metadata leakage to the backend.

Every passenger touchpoint, from booking and bag drop to gate and immigration, still relies on slow, disconnected physical document checks. VIABLE replaces this friction with a single, secure digital travel credential. Passengers move seamlessly from curb to cabin, unlocking end-to-end Modern Airline Retailing (MAR) while you slash queue times and compliance risk.

Aviation · Digital Identity Infrastructure · IATA One ID

One Digital Identity Wallet. Contactless from offer to boarding.

VIABLE seeds each traveller's Digital Identity Wallet with a biometrically-bound Verifiable Credential: IATA One ID-aligned, eIDAS 2.0-compliant, portable across borders. At every step of the journey, from Modern Airline Retailing (MAR) Offers & Orders through check-in, bag drop, gate and immigration, each actor receives only the claims their role requires, contactlessly verified. The same infrastructure carries Operational Readiness & Compliance VCs for crew, ground handlers, and inspectors. One trust layer. Zero data honeypots downstream.
