Error: “Your Card has insufficient funds“

This means that the cardholder doesn't have enough funds in the account to cover the costs of the purchase.
Sometimes, banks don’t properly assess the risk of currency conversion of purchases. If they see that the purchase is in a different currency then the bank will decline the charge as insufficient funds so the currency conversion or the currency conversion fee doesn’t overdraw the account.
If you see this error message, you should contact your bank.
