What credit card should you bring when traveling to Japan: Dual Currency Card
If you hold a China Merchants Bank credit card, UnionPay card, dual currency card or all-currency card are all supported.
There are two basic card swiping lines, UnionPay lines and international lines (VISA, MASTERCARD, JCB or American Express, etc.). When the card is swiped on UnionPay lines, the payment will be settled directly in RMB; when the card is swiped on international lines, the payment will be settled in US dollars. Since overseas consumption by credit card will be settled in U.S. dollars, if the consumption amount is non-U.S. dollars, there will be an exchange fee between the two currencies, which is 1.5% of the transaction amount. The exchange fee is collected by our bank on behalf of international organizations. If the consumption amount is in US dollars, there will be no foreign exchange settlement fee. (If you use a full-currency credit card, you can spend any money around the world with 0 currency exchange fees, the foreign exchange purchase function will be automatically activated, and you can purchase foreign exchange for repayment by spending in RMB.)
