Machine-to-machine commerce

Google Pay is evolving its payment infrastructure with the Universal Commerce Protocol (UCP) and a new server architecture. This shift aims to support transactions initiated by AI agents, moving beyond human-centric checkout processes. The updates include standardized machine-to-machine communication, a central merchant platform for data insights, enhanced Android callbacks, and expanded WebView support. This redefines customer journeys, demanding machine-readable product information and introducing cross-device biometric authentication for AI-driven transaction security.
