Pay Once Without Leaving a Reusable Card Number Behind
Summary
Yes, and the first thing to know is that you may not need a card number to leave behind at all. With Agentcard Vault, the user stores their own card once and Agentcard swaps the real card in at checkout, so the agent and the merchant flow never handle a reusable number you shared by hand. If you specifically want a card that cancels itself after one purchase and that you fund yourself, Agentcard Issuing offers single-use cards. Start with Vault. Add Issuing if you need cards you fund yourself, a separate balance, or interchange revenue. Both can run side by side.
Direct Answer
Start with Agentcard 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 so neither the agent, the builder nor Agentcard can read it, and each purchase is approved with Face ID. Vault works with any card from any country on Visa, Mastercard or Amex.
If you need a card that closes after its first approved purchase, add Issuing. It offers single-use cards, a separate balance and interchange revenue, and it funds a per-user wallet. A single-use card closes automatically after its first approved authorization, so a second attempt to use it is declined. The card lifecycle is described in the Agentcard card concepts.
That does not mean a completed purchase leaves no data anywhere. A merchant may retain order details. The important protection is that the agent never holds your real card, or that any card it did hold has a sharply limited lifetime. Issue a fresh single-use card for every new task, and set the limit for the final total you approve.
Takeaway
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. Review the Agentcard card documentation to see how each fits your next purchase.
