First of all, it is certain that as long as the shopping merchants have POS machines, cards with UnionPay and international line signs can be used for credit card consumption. Generally speaking, as long as it is not too small a business, you can spend it by credit card, including casinos.

At present, there are two basic credit card lines in Macau, UnionPay line and international line (VISA, MASTERCARD, JCB, American Express). If you swipe your card on the UnionPay line, the settlement channel of UnionPay will be automatically converted into RMB according to the latest exchange rate of the day and settled directly in RMB;

If you swipe your card on an international line, it will be settled in US dollars. Since the consumption other than credit card will be settled in US dollars, if the consumption amount is not US dollars, there will be an exchange fee between the two currencies, that is, 0.5% of the transaction amount of 65438+. If the consumption amount is USD, no settlement fee will be charged.

Therefore, when you spend money, you can ask the merchant whether there is a credit card limit of UnionPay, which can avoid the extra cost of the credit card.
