Overview
- An autonomous AI agent completed an end-to-end retail transaction—a T-shirt purchase—in a controlled Spanish setting using Mastercard Agent Pay.
- The payment was routed through Santander’s live payments infrastructure to validate operational, security and governance controls under real conditions.
- Santander and Mastercard describe the exercise as a European first but stress it remains a pilot rather than a commercial rollout.
- The framework registers and verifies AI agents and can use dedicated agent-specific tokens in place of raw card data to protect privacy and payments security.
- Executives from both firms called agentic payments a significant shift for commerce, with Santander planning broader tests and use cases as it scales.
