Where the card works

Online checkout

Any site that takes Visa. Paste the number, or let your browser fill it in.

Subscriptions

Give one service its own card, so cancelling is closing a card rather than an argument.

In a shop

Add it to Apple Pay or Google Pay and hold your phone to the terminal.

Making one

  1. Name it

    Name the card after the thing it pays for. That name is how you find it again.

  2. Fund it

    Send USDC. The card is created holding exactly what arrived, less the fee shown before you send.

  3. Spend it

    Use it anywhere Visa is accepted, and close it the moment its reason ends.

What the card does

A close view of two hands working a phone over an open laptop.

The balance is the limit

No overdraft and no credit. It spends what was put on it and then stops.

Freeze or close it

Freeze it the moment a charge looks wrong, or close it for good and issue a fresh one.

Every payment as it clears

A live list of what the card has spent, with the merchant and the amount.
