¶ Real-World Use Cases for Multi-Domain Interoperability
This page showcases real-world applications where the eTag Fuse platform enables governed, composable, and adaptive collaboration across domains — including AI, security, messaging, orchestration, compliance, and UI.
These use cases illustrate how Fuse transforms fragmented systems into orchestrated, explainable ecosystems — by connecting systems, coordinating actors, and enforcing policies through a unified, cross-domain execution model.
¶ 1. Digital Refund & Compliance Workflow
A tax refund workflow that orchestrates taxpayer intake, fraud detection, refund eligibility, bank account generation, and compliance reporting — across tax software, banks, agents, and authorities.
¶ Scenario Highlights:
- Real-time data exchange across EROs, transmitters, and tax authorities
- Risk-based AI scoring and fraud validation
- Encrypted routing of taxpayer information and documents
- Human-in-the-loop approval for flagged transactions
- Full audit trail of account creation, approvals, and refund events
Participating Domains:
¶ 2. Federated Identity Management Across Organizations
A multi-organization identity system enabling users from different providers (e.g., Okta, Azure AD, Google) to access shared apps and workflows under unified policy and role enforcement.
¶ Scenario Highlights:
- Federated SSO via SAML/OIDC and real-time identity token mapping
- SCIM-based provisioning and profile reconciliation
- Runtime governance over role scopes and MFA enforcement
- Delegated admin controls and identity lifecycle orchestration
- Consent screens, risk-based login, and compliance logging
Participating Domains:
¶ 3. In-Orbit Intelligence and Telemetry Processing
An edge-to-cloud telemetry architecture for satellite systems — where onboard AI tags and compresses mission data, then downlinks for orchestrated review and mission approval.
¶ Scenario Highlights:
- Onboard AI classifies and summarizes payloads
- Ground-based orchestration processes receive, validate, and re-route data
- Security tokens scoped by mission role and telemetry classification
- Dashboards surface telemetry events for analyst review
- Exception workflows escalate anomalies to ground-based reviewers
Participating Domains:
¶ 4. AI Assistant with Tool Discovery and Prompt Routing
A self-improving, domain-scoped AI assistant that interprets prompts, selects tools, orchestrates flows, and returns responses — governed by roles, policies, and runtime constraints.
¶ Scenario Highlights:
- Prompt understanding with fallback routing and retry logic
- Scoped execution using security tokens and resource access policies
- Real-time UI chat interface and tool execution panels
- Auditable threads with classification, scoring, and AI cost tracking
- Observability and governance over every interaction and inference
Participating Domains:
¶ 5. Cross-Border Refund & Document Processing
A multi-jurisdictional VAT refund process that captures receipts, validates travel context, and routes approvals to customs and tax authorities based on regional policy.
¶ Scenario Highlights:
- QR- and mobile-based document capture in multiple languages
- AI-powered receipt classification and fraud detection
- Region-aware refund logic based on country of purchase
- Human reviewers for document exceptions and refund approvals
- Secure document routing and audit trails for every touchpoint
Participating Domains:
¶ 6. Intermodal Asset Tracking with Real-Time Visibility
A logistics orchestration system that unifies RFID, GPS, and carrier systems to track container movement, detect delays, and alert based on policy and geo-events.
¶ Scenario Highlights:
- Real-time ingestion of GPS and port events
- AI-based delay prediction and route anomaly detection
- Handoff workflows between carriers, warehouses, and customs
- Secure token-based role scoping by carrier or port
- Dashboard visibility across the entire intermodal chain

¶ Want to Build Your Own Use Case?
Fuse lets you build domain-first — not system-by-system.
Use domains to:
- Orchestrate workflows across humans, AI, and systems
- Secure interactions using tokens, roles, and runtime policy
- Enable AI-driven logic
- Build dynamic UIs for approvals, reviews, and dashboards
- Govern messaging and notifications
- Manage knowledge and artifacts
Design your own solution — Fuse enables composable, explainable, multi-domain interoperability by default.
