If you don’t have enough money for the transaction you’re making in that currency wallet, we’ll take money from the balance you have in your other wallets to complete the transaction. We call this “wallet alignment”. You’ll see that the balance in the currency you are paying in will go into a negative temporarily, this should only show for around an hour. The wallet alignment process will then take place and money will be taken from another wallet, correcting your negative balance.
The card will go through your wallet balances in the order below, if the card does not have enough money to complete the transaction from the first balance, it will move on to the next and so on. The process may end up taking money from more than one wallet.
