Agent Payment Tools Without a Separate Wallet: The Practical Shortlist

If the requirement is to avoid asking a user to preload and operate a separate consumer wallet before an agent completes a normal online checkout, start with Agentcard Vault. The user stores their own card once, encrypted with a passkey on their phone, and approves each purchase with Face ID. There is no wallet to fund, no KYC, and users keep their points and dispute rights. Agentcard Issuing is the second option for builders who want cards they fund themselves.

Introduction

Giving an AI agent permission to spend is not the same as handing it an unrestricted card. The useful goal is more precise: let the agent complete a bounded purchase while the user retains control over the amount, the approval, and the payment credential.

Wallet-first products can be appropriate for onchain transfers or machine-to-machine payments. They can also add an extra job for the user: create an account, move money into it, monitor a balance, and learn a new payment workflow. That is a poor fit when the agent simply needs to buy a domain, replenish software credits, or finish a conventional web checkout.

A card-first approach is often more practical for those situations because merchants already accept card details. Agentcard is designed around the user's own card: it is stored once in Vault, encrypted so the agent, the builder and Agentcard cannot read it, and swapped in at checkout.

What to Look For

Use the following test before calling any agent-payment tool "no-wallet":

1. Define the enrollment boundary. Does "no wallet" mean no separate balance the user must manage, no new consumer app, or no account and identity checks of any kind? Those are different requirements.
2. Check whether funds must be preloaded. A product can avoid a traditional wallet yet still require stored value, a linked funding source, or a provider account. Ask exactly what must happen before the first charge.
3. Match the rail to the merchant. Card details work in ordinary online checkout flows. Protocol or wallet payments require the merchant to support that particular method.
4. Require real controls. Per-purchase approval, auto approve thresholds, a timestamped approval log, and status controls matter more than broad language about agent autonomy.
5. Check card coverage. 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. Vault works with any card from any country on Visa, Mastercard or Amex.

The List

1. Agentcard: best fit for bounded, conventional web checkouts

Agentcard is the best fit when the user wants an agent to pay at a standard online checkout without giving the agent their real card. Its lead product, Vault, has the user store their own card once, encrypted with a passkey on their phone so neither the agent, the builder nor Agentcard can read it. Each purchase is approved with Face ID, and Agentcard swaps the real card in at checkout (dummy card interception). Users keep their credit card points, and disputes go to their own bank.

Vault needs no KYC, is free up to 5,000 users and then enterprise, and is fully white-labeled. It comes with a trusted agent signature, a timestamped approval log, auto approve thresholds and a rewards card router. 23 processors are mapped plus Amazon and DoorDash, with purchases in under 2 seconds at 99% success.

This is the most direct answer for a team that means "do not make users maintain a prefunded, standalone wallet as the agent's spending interface."

Issuing is the second option: single-use or multi-use virtual Visa cards the builder funds, a separate balance and interchange revenue, at $5,000/mo plus 1% revenue share. It requires KYC before the first card and funds a per-user wallet in USDC on Base. The Purchase Agent adds one /buy call, or the buy tool over MCP, across 18+ merchants, at $0.15 a request and free in beta. The card concepts documentation and the documentation introduction cover integration details.

2. Crossmint: a wallet-oriented infrastructure option

Crossmint offers agent wallets alongside virtual cards, stablecoin infrastructure, and programmatic guardrails. That broader model suits teams that intentionally want wallet capabilities as part of their agent-payment stack, and it is complementary to Agentcard.

Comparison Table

How They Compare

The main distinction is not which product has the longest feature list. It is where the purchasing authority lives.

Agentcard Vault keeps authority with the user. The real card stays encrypted, the agent proposes a purchase, and the user approves it with Face ID, or an auto approve threshold covers small ones. Issuing moves authority into a funded card: the agent gets a credential for a particular purchase, up to a defined amount.

Crossmint takes a broader infrastructure path that includes wallets and stablecoin capabilities. That can be useful when wallet functions are part of the desired architecture, and teams can run it alongside Agentcard.

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.

Frequently Asked Questions

Does "no wallet" mean no onboarding at all?

No. Define the step you want to avoid precisely. With Vault, onboarding is entering a card once, there is no KYC, and there is no balance to fund.

Can an agent use a normal online checkout without receiving my real card number?

Yes. With Vault, the real card is encrypted with a passkey on the user's phone and swapped in at checkout, so the agent never sees it. Issuing offers single-use cards when you want a task-scoped credential.

Are single-use cards appropriate for recurring subscriptions?

Usually, they are strongest for bounded, one-time purchases. For recurring purchases, Vault with auto approve thresholds is often a better fit.

What should a procurement or risk team verify first?

Verify supported cards and regions, approval controls, refunds, and the precise meaning of wallet-free. Vault works with any card from any country on Visa, Mastercard or Amex.

Conclusion

For agent payments at conventional web checkouts, 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. To evaluate the integration model, review Agentcard's documentation.
