Interoperability, the ability for systems to connect and work together, allows for e-mails that pass effortlessly around the world and trains that travel between cities no matter who laid the tracks. Yet interoperability remains largely absent from the financial services used most frequently by the poor.

This blog series provides CGAP's views on the value proposition provided by interoperability; best practices in scheme governance, business models, and technology; and what steps can be taken to achieve effective, pro-poor interoperability for digital financial services. A supplementary publication and a paper to this blog series are available in FinDevGateway.
