Visa is moving to let artificial intelligence agents swipe your credit card. The payments giant has begun testing a system that allows AI assistants like ChatGPT to initiate payments directly on behalf of consumers using a tokenized credential.

How the Payment Token Works

The new service, called Visa Tokenized Credential, creates a unique digital token linked to a user's Visa card. Instead of sharing the actual card number with an AI agent, the token acts as a stand-in that can be authorized for specific transactions, merchants or spending limits. The token is designed to be revocable, giving users control over when and where the AI can spend money.

Visa executives say the system addresses a core security problem: AI agents lack the ability to use standard payment verification methods like CVV codes or one-time passwords. By issuing a token with built-in constraints, Visa aims to close that gap without forcing consumers to hand over full payment credentials.

Why This Matters

If widely adopted, this technology could fundamentally change how people shop online. Consumers could instruct an AI agent to find the best price on a product and complete the purchase without clicking a single button. That convenience carries serious risk. Fraudsters could potentially hijack an agent's token or trick the system into approving unauthorized payments. The pilot is a test of whether consumers will trust an AI to make spending decisions on their behalf.

The move also signals that major financial institutions see AI agents as a permanent part of the digital commerce landscape. Visa processes trillions of dollars in transactions annually. Its willingness to build payment rails for AI agents suggests that autonomous spending is not a fringe concept but a near-term reality.

Security Concerns and Open Questions

Security experts point out several unresolved issues. An AI agent could be manipulated through prompt injection attacks to bypass spending limits. Malicious actors might create fake merchant profiles that trigger payments to themselves. Visa has not disclosed the full details of its token revocation mechanism or how it will handle disputes when an AI agent makes an unwanted purchase.

The system also raises privacy questions. To authorize payments, the AI agent must communicate with Visa's network, creating a new data trail linking a person's AI interactions to their spending habits. Visa says it will not use voice data or conversation logs for marketing purposes, but the data flow itself could become a target for surveillance or subpoenas.

The Broader Push for AI Commerce

Visa is not alone in pursuing AI-driven payments. Mastercard runs a similar tokenization pilot for AI agents. Companies like Instacart and Walmart have experimented with AI assistants that manage grocery orders. The difference with Visa's approach is the emphasis on a standardized token layer that works across merchants, potentially turning any AI chatbot into a universal shopping tool.

That ambition places Visa at the center of a regulatory gray zone. Current consumer financial protection laws were written for human decision makers. Assigning liability for AI-generated purchases is an unsettled question. If an agent buys the wrong item or makes a fraudulent transaction, who pays? Visa says its token system allows consumers to set hard spending caps and merchant whitelists, but the legal framework lags behind the technology.

For now, the pilot remains small, limited to a handful of merchants and AI platforms. Visa has not announced a public launch date. The company is likely watching user behavior closely to gauge whether the convenience of AI shopping outweighs the inherent risks. The outcome of this experiment could shape how billions of dollars flow through e-commerce in the coming years.
