This paper explores possible responses to some of the main challenges associated with conducting elite and expert interviews as part of qualitative research in human geography. Drawing on the example of the dynamic fintech industry, the paper outlines some similarities and differences between elite and expert interviews and uses this to identify and discuss possible responses. Against this backdrop, the paper also reflects on advantages and disadvantages of using the professional social networking site LinkedIn as a research aid for sampling and contacting interviewees as well as for interview preparation. The paper is anticipated to be of interest to those conducting qualitative research involving limited size sample subjects who are potentially difficult to find.

This article explores how transaction information is a fundamental element enabling and fostering global flows of money. Financial systems, constructed around account-based money, require infrastructure, which is separated into two parts: messaging and settlement, performed via trusted agents. This separation has allowed the geographical expansion of banking, and to this day constitutes a key architecture of increasingly global networks of money. Focusing on the correspondent banking system and the Society for Worldwide Interbank Financial Telecommunication, this article demonstrates the workings of this infrastructure in cross-border payments and in enacting economic sanctions. This sociotechnical infrastructure is a crucial yet overlooked area of global banking, which makes global economic and financial activity possible in the first place. Importantly, by analysing the organizational architecture of the global payments system and including the actors and agencies within it, we elucidate the (changing) relationships between data/information, geographies and power, contributing to the formation of a literature that conceptualizes financial infrastructure.
