Home Nautilus Open Architecture

Open Architecture

Nautilus is designed to keep options open. The system can work with multiple processors simultaneously and send transaction data to multiple services, such as fraud screening, FX booking, or any additional service required. It can involve multiple services in authorization decisions, distribute transactions to several internal systems, and execute services in sequence or in parallel. The most important of all, Nautilus’s open architecture allows new processors and services to be integrated as needed.

Flexible

Nautilus supports multiple processors simultaneously, enabling different providers to be used for separate territories or product lines. New processors can be added as business needs evolve, without interrupting existing operations. This flexibility ensures the architecture can adapt smoothly to growth and changing requirements.

Extensible

Nautilus is built to evolve with changing needs. New services—whether fraud screening, FX booking, or technologies that don’t exist yet—can be added seamlessly into the transaction flow. Because these integrations don’t depend on changes from processors or schemes, they can be introduced quickly and with minimal effort, ensuring the system is always ready for what comes next.

Interoperable

Nautilus can distribute transaction data to multiple internal systems on the issuer side, supporting both processing decisions and reporting needs. Data can be combined using logical rules such as AND or OR for authorization purposes, or routed to different systems for storage, analytics, and regulatory reporting. This ensures seamless integration across the bank’s internal ecosystem without additional custom development.
