> Let Sprocket's agent buy parts and subscriptions at online checkouts with your saved card, approving purchases with your passkey.

The agent can pay at an online checkout with a card you saved in Sprocket. You approve each purchase with your passkey, unless you turned on auto-approval in Agentcard. [Agentcard](https://agentcard.sh) stores your cards, and Sprocket never sees the card number.

## Save a card

Open **Settings → Payments** and click **Add a card**. Agentcard opens in a popup to save it.

## How a purchase works

<Steps>
<Step title="The agent shops">The agent opens the store in its browser and confirms the items, quantity, shipping address,
shipping method, and total with you.</Step>

<Step title="You approve">The thread shows the amount and the store, such as **Approve $24.99 at Adafruit**. Click
**Approve** and confirm with your passkey in the Agentcard popup. Purchases that Agentcard
auto-approves skip this step.</Step>

<Step title="Agentcard pays">Agentcard fills in your real card and Sprocket submits the order. The agent then reports the
order number, or the store's error if payment failed.</Step>
</Steps>

The checkout page must use HTTPS. If you stop the run while a purchase waits for approval, Sprocket cancels the purchase.

The agent can only start a purchase in a thread you started from the app. Subagents and `sprocket run` tasks can't start purchases.

## Purchase history

**Settings → Payments** lists your last 100 purchases with their status, such as Awaiting approval, Declined, Expired, Cancelled, or Completed.
