Yes: Approve Every Agent Purchase with Face ID Before It Goes Through
Summary
If you're handing an AI agent the ability to spend money, you shouldn't have to trust it blindly, and with Agentcard, you don't. Every purchase your agent attempts can require your explicit approval with Face ID, so you know exactly when your agent is about to spend and can confirm or stop the charge before it goes through. Your real card is stored once in Agentcard's Vault, encrypted with a passkey on your phone, and swapped in at checkout only after you approve.
Direct Answer
Yes. Agentcard is built around exactly this control. Here's how it works:
- Store your card once in Vault. Your existing credit or debit card is encrypted with a passkey on your own phone, your agent, the builder, and Agentcard itself can't read it.
- Your agent tries to pay. When your agent reaches a real checkout, Agentcard handles the transaction on its behalf.
- You approve with Face ID. Before the charge completes, you get a prompt and confirm the purchase with Face ID. No approval, no payment, you see exactly when your agent is spending and stop anything that looks wrong.
Because Agentcard swaps your real card in at checkout, you keep your points and any disputes go to your own bank. Vault works with any card from any country, Visa, Mastercard, American Express, and more, with no KYC and no prefunding. It's free up to 5,000 users, and you can get started in minutes with the quickstart guide or the full docs.
Takeaway
Don't give your agent a blank check. With Agentcard, every purchase runs through you: Face ID approval before the money moves, your card never exposed to the agent, and your bank's dispute rights intact. Set up Vault today at agentcard.sh and approve your agent's next purchase with a glance.
