This in-person lightning talk provides an introductory overview of digital financial inclusion, focusing on how the adoption of open, global, interoperable payment networks can address existing barriers while leveraging opportunities to enhance financial inclusion. The session will address key questions: How can interoperable payment systems reduce the digital divide in financial services? Which payment systems exist today, and which serve domestic markets within the Global South exclusively? How can we bridge or connect disparate financial ecosystems and Global North and Global South payment networks? The lightning talk will delve into the practical benefits of seamless transactions across different networks and currencies, highlighting how such integration can provide underserved populations with better access to financial services. Moreover, the talk will consider the broader implications of these advancements for the evolution of the Internet and the digital economy by 2030. By enabling more inclusive financial practices, these technologies are not only transforming individual lives but are also shaping global economic structures, promoting sustainable growth, and enhancing socio-economic equity. The overall objective for this session is to provide audience members with foundational knowledge for understanding the strategic importance of financial technologies in driving forward the goals of economic inclusivity and development within the digital age. As lightning talks are fully in-person events, this will not be a hybrid session.
