COIN
The COIN is next generation connectivity for Australian payments.
The Community of Interest Network (COIN) is a high availability, managed network for the multilateral secure transmission of payment files between payments participants.
Designed as collaborative core infrastructure for the future of Australia’s low-value payments, the COIN provides an alternative to point-to-point connectivity between payments participants.
Currently the COIN provides network services and connectivity for our frameworks for cheques, direct entry, and domestic cards. It also provides the network for BPAY bill payments and PEXA financial settlements.
The COIN operates independently from all other payments frameworks and is open to all participants in the payments system. We provide the rules, procedures and decision-making framework enabling participation in the COIN.
In 2024 the COIN network service was upgraded, with Transaction Network Services Australia (TNS) providing a highly diversified, highly redundant dual-carrier network, with enhanced speed, operational and security benefits.
The COIN is a closed virtual private network for the secure transmission of payments related messages and files between participants.
Common Payments Network
We established the COIN as part of a wider physical connectivity network for payments. In addition to the COIN, the CPN includes the SWIFT network, and the Reserve Bank’s (RBA’s) clearing interconnector which enables payments traffic to pass between the COIN and SWIFT.
Together, the COIN, the RBA Network Interconnector and the SWIFT FileAct Service provide for a common payments network in Australia.
