FAQQuestions

What is the BIAN “Operate” functional pattern?
An Operate service domain keeps a piece of operational or technical capability running day to day. Card Network Participant Services applies it to the Card Network Membership.
What is a BIAN service domain?
BIAN (the Banking Industry Architecture Network) decomposes a bank into independent service domains, each owning exactly one business capability. Card Network Participant Services is the service domain for Cards; it manages the Card Network Membership Operating Session and exposes it through standard BIAN action terms.
What business area does Card Network Participant Services belong to?
Card Network Participant Services sits in the Operations and Execution business area — the operational core that executes payments, positions, settlements and transactions. It runs in the bian-operations namespace as one independent Spring Boot microservice.
Is Card Network Participant Services production-ready?
It is an educational reference implementation: a real BIAN REST API over an in-memory store, ready to be filled with domain logic. It is not a live bank and is not affiliated with BIAN.
