KAST makes it easy to spend your crypto in the real world - in any store, café, or restaurant that accepts PIX or Visa.

How Do I Spend My Crypto in Brazil Using PIX?

The KAST app makes it easy to spend your crypto balance at any merchant in Brazil that accepts PIX.

1. Scan the QR Code: Open the KAST app and scan the merchant’s PIX QR code at checkout.
2. Review and Confirm: Your KAST app shows the BRL total the merchant receives and the equivalent USD amount deducted from your balance.
3. All Done: The merchant receives BRL instantly.

What Are the KAST Card Fees When I Pay in Brazil?

When you pay in BRL, KAST handles the conversion from USD → BRL using a transparent market-based rate plus a 2% FX fee.

If you choose to pay in USD (when available), some merchants may use Dynamic Currency Conversion (DCC) - applying their own exchange rate, which is often higher than KAST’s.

There’s no standard transaction fee per purchase (including Apple Pay and Google Pay).
However:

• A $0.50 declined transaction fee applies only if your payment fails due to insufficient balance.
• For non-USD transactions below $25, a small $0.10 low-authorization fee may apply.

PIX Scan to Pay

When you use PIX Scan to Pay, your crypto is converted instantly to BRL at the market rate. There’s no transaction fee for the payment itself.

When depositing via PIX, customers are charged a total FX markup of 0.88%.‍

For PIX payouts, there’s a 1% conversion fee total.

Which Receipt Option Should I Choose at the Terminal?

When paying with your KAST Card or mobile wallet (Apple Pay / Google Pay), the terminal may ask if you want to pay in BRL (Real) or USD (Dollar).

Although it might seem logical to choose USD if your balance is in dollars, in Brazil we recommend almost always select BRL (Real).

Why You Should Choose BRL

• Most merchants only process BRL, even if you choose USD.
• Selecting USD triggers Dynamic Currency Conversion (DCC) by the merchant or processor - using their own (often worse) exchange rate.
• Selecting BRL lets KAST handle the conversion, applying a transparent market-based rate + up to 2% spread.

Example: Paying in Brazil - BRL vs USD

Here’s an example from a coffee shop in Blumenau, Santa Catarina, where the same R$7.50 item was paid twice - once selecting BRL, and once USD.

Option 1: Paying in BRL (Recommended)

Option 2: Paying in USD (Merchant Conversion)

Cost Comparison Summary

Tip : When paying in Brazil, always choose BRL (Real) at the terminal. This ensures KAST - not the merchant - handles your currency conversion, usually resulting in a lower overall cost and more transparent rates.
