Withdrawal: Please confirm whether the ATM accepts your credit card type (visa/master/amex). There is usually a sign above the ATM. If not, you can ask the bank first.
In addition to cash withdrawal, it can be used anywhere that accepts credit card consumption, such as some big shopping malls and hotels. If you are not sure, you can consult the merchant first.
And the amount on the day of consumption is settled according to the exchange rate of the day.
