Your KAST card is designed for global, everyday spending. In this article, you’ll learn where your KAST card works, where it may not be accepted, what to expect at checkout, and how to troubleshoot declined transactions.
Where Can I Use My KAST Card?
Your KAST card runs on the Visa network, which means it can be used anywhere Visa is accepted, both online and in-store.
This includes:
- Retail stores and restaurants
- E-commerce platforms
- Travel websites and airlines
- Subscription services
- ATMs displaying the Visa logo
- Mobile wallets like Apple Pay or Google Pay (where supported)
If a merchant accepts Visa, your KAST card should work.
Are There Any Places Where My Card Won’t Work?
While your KAST card is widely accepted, there are some limitations.
Your card may not work if:
- The merchant does not accept Visa.
- The merchant is in a restricted category under card network rules.
- The transaction exceeds your available balance.
- You are attempting a transaction type that is not supported (for example, certain offline terminal authorizations).
- You are using an unattended payment terminal, such as an automated fuel dispenser, which is not currently supported for security reasons. If you're purchasing fuel, pay inside the station instead.
If you're unsure whether a merchant accepts Visa, look for the Visa logo at checkout or on the payment terminal.
Can I Use My KAST Card Internationally?
Yes. Your KAST card is built for global use.
You can:
- Pay in foreign currencies
- Shop with international merchants
- Withdraw cash abroad at Visa-supported ATMs
If you’re making a purchase in a currency other than USD, KAST automatically handles the currency conversion. Applicable foreign exchange (FX) fees range between 0.5% and 1.75%, depending on the country and currency.
To get the best rate:
- Always choose to pay in the local currency
- Avoid “Pay in USD” options offered by third-party terminals
Can I Use My KAST Card Online And With Mobile Wallets?
Yes. Your KAST card works:
- Online at any merchant that accepts Visa
- In apps and subscription platforms
- With Apple Pay and Google Pay (where available)
To add your KAST card to a mobile wallet, follow the step-by-step guides below for your device:
For Apple Pay: See How Do I Add My KAST Card to Apple Pay?
For Google Wallet: See How Do I Add My KAST Card to Google Wallet?
Each guide walks you through adding your card, completing verification in the KAST app, and confirming your wallet is ready to use.
Once added, you can pay contactlessly in stores or in supported apps.
What Should I Do If My Card Is Declined?
If your KAST card is declined, follow these steps:
- Check your available balance in the KAST app.
- Confirm the merchant accepts Visa.
- Ensure your card is active in the app.
If everything looks correct and the issue continues, contact KAST Concierge with the transaction details so the team can review it.
