China Merchants Bank’s credit cards include RMB single-currency credit cards and RMB-USD dual-currency credit cards. Cards with only UnionPay or overseas credit card organization logos on the card are single currency cards. In addition to the UnionPay logo, dual-currency credit cards also have the logos of overseas credit card organizations, such as Visa, Master, JCB, and American Express Blue Label, which are dual-currency credit cards. Dual-currency cards make it easier for you to choose a line with the logo of an overseas credit card organization for consumption overseas.
