Swipe cards on UnionPay lines, settle in RMB, and repay in RMB;
Swipe cards on international lines, settle in U.S. dollars, and repay in U.S. dollars, or activate the credit card purchase and repayment function.
Warm reminder
When taking the international route, consumption is settled in U.S. dollars (except credit cards in all currencies). Therefore, if the consumption amount is non-U.S. dollars, there will be an exchange fee between the two currencies ( Approximately 1.5% of the transaction amount). If the UnionPay line is used or the consumption amount is US dollars, there will be no foreign exchange settlement fee. When swiping cards overseas, it is recommended that you choose UnionPay channels.
