Visa explains passkey and Trusted Agent Protocol checks for AI shopping agents

Visa's Aditya Bhamu explains how payment passkeys and Visa's Trusted Agent Protocol verify purchases made by AI shopping agents.

According to the report, the system is designed to tell legitimate agents apart from malicious bots, so merchants can confirm that an agent has the user's permission. The report is a post on X by NVIDIA AI that relays Bhamu's explanation; it does not describe how the system performs in practice.
