Primary currency: Your card’s primary currency is GBP for UK clients or Euro for Eurozone clients. We convert your assets to your primary currency when you spend. Refunds and reversals are also paid in your primary currency. If you’re using other assets in a transaction and they fail, we’ll try to complete the payment using your primary balance.
Small balances: Balances under £1 or €1 in your Everyday balance may be skipped when spending as they can’t always be converted.
Block: You can block specific currencies if you don't want to use them to spend.
Unavailable: Some assets are unavailable for payments and they’ll appear in the Unavailable section. If that changes, they’re automatically added to the bottom of your spend order and will be available for spending.
