Visa is launching a Trusted Agent Protocol to protect merchants from fraudulent bots during transactions with AI agents. This protocol uses cryptographic signatures to verify trusted agents and secure transactions, allowing AI to make purchases on behalf of consumers. It aims to enhance confidence in the agentic commerce ecosystem.

Fiserv has teamed up with Visa and Mastercard to provide merchants with AI-driven commerce tools. These tools will help identify legitimate AI shopping agents and enable secure transactions, although access dates for merchants are still unclear. This move reflects a growing trend in agentic commerce, where AI agents assist in shopping.
