Accelerate your migration from legacy CORBA systems to modern, web-native self-service. CUSS2.dev is the industry-leading hub for TypeScript, Angular, and React SDKs designed specifically for the IATA RP1706c specification.
As of January 1, 2026, CUSS 2.0 is the official global mandate for common-use self-service. Legacy architectures based on CORBA have reached end-of-life, transitioning the industry to a modern, web-native ecosystem.
Built on OpenAPI and WebSockets, moving away from legacy CORBA/IDL for true cross-platform compatibility.
Mandatory TLS 1.2+ encryption and OAuth2 authentication are baked into the core protocol.
Decouples hardware from software, allowing standard web developers to build airport apps with 40% less overhead.
As members of the IATA CUSS Task Force, Elevation AI provides the world-class tooling required to navigate this transition. Connect with us on LinkedIn for technical updates.
As of January 1, 2026, the industry has moved from legacy proprietary systems to an open, web-first architecture.
| Technical Pillar | Legacy CUSS 1.x | Modern CUSS 2.0 |
|---|---|---|
| Communication Protocol | CORBA / IDL (Proprietary) | WebSockets & OpenAPI |
| Security Model | Perimeter-based / Trust-all | Zero-Trust (OAuth2 / TLS) |
| Deployment Method | Local OS Installation (.msi / .exe) | Pure Web App (Cloud-Native) |
| Hardware Access | Synchronous Middleware | Asynchronous Hardware Events |
| Data Exchange | Binary / Fixed-Length | JSON / YAML (Standardized) |

RP 1706c represents a total
architectural pivot from CORBA-based binary protocols to a modern web-standard stack. It eliminates the
"fat-client" installation requirement, enabling pure web applications to communicate with airport
peripherals via standardized JSON payloads and WebSockets.
Moving from legacy CORBA architectures to modern web-native environments requires a strategic shift in application design.
Deprecate CORBA/IDL bindings and transition to WebSockets and OpenAPI for device communication.
Implement mandatory OAuth2 authentication flows and ensure all traffic is encrypted via TLS 1.2+.
Adopt JSON Web Tokens (JWT) for session management and application identity within the CUSS2 runtime.
Map legacy data structures to the new JSON/YAML standard payloads required by the TypeScript SDK.
We strongly recommend architecting your CUSS2 application as a pure web app. This eliminates the need for proprietary software installation on the physical kiosk, dramatically reducing maintenance and security risks.
Complete software development kits for CUSS 2 applications with TypeScript, Angular, and React support, plus an interactive development sandbox for testing airport self-service solutions.
