"Agentic AI is becoming one of the UK’s biggest commercial opportunities. They chose the UK to announce expansion of Agent Suite with Proto, a sandbox environment to explore, test and validate agentic AI use cases before introducing them into production. Mastercard will be live in the UK in August. Retailers and their partners will be able to test whether their products are discoverable by agents, how to scale the payment experience, whether their plan for handling disputes in this environment works at scale, and much more."
