our credit cards can be used normally in Hong Kong, Macao and Taiwan. At present, there are two basic credit card lines in Hong Kong, Macao and Taiwan, namely UnionPay line and international line (VISA, MASTERCARD, JCB or American Express, etc.). Credit card swiping on UnionPay line will be settled directly in RMB; If you swipe your card on an international line, it will be settled in US dollars. Since the consumption outside the 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 (1.5% of the transaction amount). If the consumption amount is USD, there will be no settlement fee. When you consume, you can ask the merchant whether there is a UnionPay credit card line to facilitate your choice.
