Visa just launched a protocol to secure the AI shopping boom — here’s what it means for merchants
Visa has introduced the Trusted Agent Protocol to address the challenge of distinguishing legitimate AI shopping assistants from malicious bots. This protocol establishes foundational infrastructure for agentic commerce, where AI agents autonomously search, compare, and purchase products. Merchants can now cryptographically verify that these AI agents are authorized and trustworthy, preventing data scraping and fraud. AI-driven traffic to retail sites has surged drastically, overwhelming existing bot detection systems. Visa's protocol uses a cryptographic trust handshake, requiring AI agents to be vetted and receive a unique digital signature key. Approved agents then transmit information about their intent, consumer recognition, and optional payment details. Merchants validate these signatures to confirm the agents' trustworthiness, with minimal changes to existing infrastructure. Visa is collaborating with companies like Cloudflare and engaging with competitors like Google and OpenAI to establish industry standards. The protocol raises questions about liability for unauthorized transactions, but Visa emphasizes its fraud protection systems. Visa's gatekeeping role in approving AI agents could be contentious, potentially favoring larger companies. The protocol launches amidst Visa's legal challenges regarding credit card swipe fees and debit card routing investigations. Visa acknowledges that widespread adoption will take time, focusing on building credibility and demonstrating value. Analyst predictions suggest merchant adoption will depend on the growth of AI agents in completing transactions. Visa's investment in AI for fraud reduction and its expansion into new payment areas, like partnering with X for a digital wallet, underscore its strategic focus on AI.
