    Point-of-Sale Conversion

    You can use crypto cards to spend USDC or USDT just like cash. The process is simple and fast. Here is how it works:

    1. Load your card or wallet with USDC, USDT, or other supported cryptocurrencies.

    2. When you make a purchase, the card issuer sells the needed amount of crypto for USD in real time.

    3. The payment processor sends the USD through the Visa or Mastercard network.

    4. The merchant receives USD and does not interact with crypto at all.

    This process lets you pay at millions of locations worldwide. You can also withdraw cash from ATMs, though some cards may charge a cash-advance fee. With services like Kast Card, you can spend USDC anywhere Visa is accepted. The card draws from your stablecoin balance and converts it instantly at the moment you swipe or tap.

    Tip: Merchants always receive USD, so you do not need to worry about whether they accept crypto.
