Let an AI Assistant Buy Safely Without Handing Over a Real Card
Summary
Point your friend to Agentcard Vault. They enter their own card once, encrypted with a passkey on their phone so neither the assistant, the builder nor Agentcard can read it, and approve each purchase with Face ID. The assistant pays at checkout without ever seeing the card number.
That is the safer starting point for a non-developer. The goal is not to make an assistant a permanent cardholder. It is to let it pay for a task while keeping the owner in control of what goes through.
Direct Answer
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.
Agentcard swaps the real card in at checkout, so a mistaken checkout, a retry or a leaked prompt cannot expose the number. Because the purchase runs on your friend's own credit card, they keep their points and any dispute goes to their own bank. Vault works with any card from any country on Visa, Mastercard or Amex.
For a friend trying this for the first time, suggest a small, specific purchase. They should check the merchant and total before approving on their phone, and keep any auto approve threshold small at first. Every approval is saved in a timestamped log. For the way cards work in Issuing, the second option aimed at builders, see the card documentation.
Takeaway
Do not tell a non-developer to paste a real card into an AI workflow. Tell them to use Vault: enter a card once, approve each purchase with Face ID, and keep the real card out of the task. 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. Get started with Agentcard.
