The work builds on Visa Trusted Agent Protocol, Mastercard Verifiable Intent and Ant’s Agentic Mobile Protocol, and will proceed through MAS-convened BuildFin.ai and the SAFR runtime-safeguards effort. The companies cite a McKinsey projection that AI agents could orchestrate US$3 trillion to US$5 trillion of global consumer commerce by 2030; that figure is their cited third-party forecast, not a zFinia measurement. No implementation timetable, merchant pilot list or settlement volume was published.","whyItMatters":"Consumer-agent checkout is colliding with the identity problem: merchants need to know which software is acting, for whom, and under what authority.
