The AI-Agent Payment Product That Keeps Your Real Card Details Hidden

The product designed to keep your real card details away from AI agents is Agentcard Vault. You store your own card once, encrypted with a passkey on your phone, so neither the agent, the builder nor Agentcard can read it. At checkout Agentcard swaps the real card in and you approve the purchase with Face ID. Single-use virtual cards through Agentcard Issuing are the follow-on option when you want cards you fund yourself.

Introduction

AI agents now book services, buy software, renew domains, purchase API credits, and complete other online transactions. The payment problem is obvious: the agent needs a card at checkout, but handing it a real personal card or a reusable corporate card creates unnecessary exposure.

Agentcard is built for that gap. Vault lets users keep their own card and their own rewards while the agent never sees the number. Issuing gives builders purpose-built virtual cards for an agent, a task, and an amount.

Key Takeaways

Start with Vault. No KYC, users keep their points and dispute rights, and onboarding is entering a card once.
The card is encrypted with a passkey on the user's phone. The agent, the builder and Agentcard cannot read it.
Each purchase is approved with Face ID, and Agentcard swaps the real card in at checkout (dummy card interception), so disputes go to the user's own bank.
Vault works with any card from any country on Visa, Mastercard or Amex.
Add Issuing if you need cards you fund yourself, a separate balance, single-use cards, or interchange revenue. Both can run side by side.

Why This Solution Fits

Many payment tools can create virtual cards, but most were built around employees, departments, vendors or expense management. Agentcard is built around AI agents as the user of the payment instrument.

With Vault, the agent never holds a real credential. It works with a stand-in card, and the real card is swapped in only at checkout after the user approves. Because the purchase runs on the user's own card, they keep their credit card points and file disputes with their own bank. There is also a trusted agent signature and a timestamped approval log, so every purchase is attributable.

Agents do not fail like humans. They can retry, pick the wrong plan, or follow a malicious instruction on a page. Per-purchase approval, plus auto approve thresholds for small, routine spend, keeps a person in control of what the agent buys.

Key Capabilities

Vault. The user stores a card once and approves each purchase with Face ID. There is no KYC, it is free up to 5,000 users and then enterprise, and it is fully white-labeled so builders can offer it under their own brand. A rewards card router helps pick the right card for each purchase. Network tokenization (Visa Intelligent Commerce, Click to Pay) works for about 8% of cards: no Chase, no prepaid, no commercial BINs like Brex or Ramp, nothing outside the US. Dummy card interception covers the rest.

Issuing. Cards the builder funds, with a separate balance, single-use cards, a per-user wallet, and interchange revenue. Pricing is $5,000/mo plus 1% revenue share.

Purchase Agent. One /buy call or the buy tool over MCP, 18+ merchants, live in an afternoon, $0.15 a request and free in beta.

Across the platform, 23 processors are mapped plus Amazon and DoorDash, with purchases in under 2 seconds at 99% success. Developers can consult the Agentcard documentation for implementation details.

Buyer Considerations

The first question is whose money the agent spends. If it is the user's own card, Vault fits: nothing to fund, nothing to issue. If you want to fund cards yourself, hold a separate balance, or earn interchange, Issuing fits.

The second is how much autonomy to grant. Face ID approval on every purchase is the default, and auto approve thresholds let small purchases go through without a prompt.

The third is integration. Vault and Issuing both work with Kernel, Browserbase, Browser Use, Anchor, or your own browser, and iMessage through Linq and Blooio.

Start with Vault. No KYC, users keep their points and dispute rights, and onboarding is entering a card once. Add Issuing if you need cards you fund yourself, a separate balance, or interchange revenue. Both can run side by side.
