How to deploy AI to improve job performance is important for most of us. We use AI to help our website provide value to visitors but not to write articles or generate statistics. Working with AI reminds us of what it can’t do but we humans can. One example in this issue: we contacted other humans and obtained their statistics in our report on US debit cards. Another is curating a mix of timely articles based on interviews with fellow humans. In this issue, our interviews involved API-based merchant acquiring, eliminating 80% of the time needed for fraud reviews, providing cardholders with financial protection against mistakes made by AI agents, issuing commercial Visa cards settled using stablecoins and protecting against criminals who deploy false identities. Note: the report and articles identified amount to only half of the information available in this issue. We invite you to explore every page.
