About

Independent analysis of payments, behaviour and the quiet plumbing of finance.

Updated 26 February 2025.

Transaction Intelligence is independent long-form analysis on payments, behaviour, and the systems most fintechs pretend aren't there — written by someone who's worked inside them, for readers who want the operational truth rather than the press release.

What you'll find here

Six categories, deliberately broad:

  • AI & Automation — the model-shaped change happening inside risk, authorisation and the back office
  • Payments — rails, schemes, ISO 20022, and the operational reality of moving money
  • Banking Technology — the unfashionable infrastructure most of finance still runs on
  • Financial Behaviour — mental accounting, household money flows, and the social meaning of a transaction
  • Regulatory — DORA, PSD3, FiDA, and the supervisory letters nobody publishes
  • UX & Design — where service design meets the awkward bits of money

Who writes it

Matt Berryman. Twenty years across issuers, schemes, and the awkward bits in between. I write here because what I read elsewhere is either marketing or a trade-press summary, rarely the operational truth I see day-to-day.

“The best newsletter on payments I read. The only one that bothers with the boring bits, which is where the interesting bits live.”
Head of Strategy, UK challenger bank
