   "synopsis": "An argument that payment rails are never neutral plumbing. They are instruments of state power, and the contest over who runs them is a contest over sovereignty itself. Rigden works through fintech the way a defence analyst works through an arsenal, tracing how card schemes, instant payments, wallets and digital currencies are used to project influence, enforce sanctions and redraw the boundaries of financial control. The result reads as a field guide to the battle for global dominance being fought through the machinery of money, where every scheme announcement is a move on the board.",
   "shelf_note": "This one is personal. I was one of the few people who helped edit the book, and a small contributor to some of what is written in it, so I watched the research being assembled from the inside. For me it is the mandatory book on fintech, though fintech undersells it. Rigden writes about hegemony, statecraft, balance of trade and the geopolitics of payment rails at a level the industry rarely attempts. Working on it sharpened my own appetite for writing and for helping inform, educate and share ideas, and it remains the book I hand to anyone joining the payments industry."

The schemes that win, from Visa's member model to UPI's stack, are the ones built alongside the people who use them, not handed down to them, and his thinking on co-creation and co-intelligence still shapes mine.

Dynamic pricing and work allocation look elegant from the platform's side and rather different from the driver's seat.
