Single-currency credit cards are credit cards with only a single settlement currency, and traditional credit cards belong to this type. Credit cards can be classified in many ways. If divided by currency, it can be divided into single currency card and dual currency card. So in China, we can say more precisely that money can be divided into dual-currency cards and RMB cards, and dual-currency cards generally refer to US dollars, RMB or Euro and RMB.
