The settlement process of the international credit card online payment channel is as shown in the figure:

No matter whether it is abroad or abroad Regardless of the currency used for settlement, the bank will convert it into the corresponding RMB amount based on the current exchange rate and record it into the account. The customer only needs to pay back the RMB account after returning. And if the customer goes to a country that does not settle in U.S. dollars or Euros, according to the original practice of traditional dual-currency cards, the customer's consumption is first converted into U.S. dollars in the local currency and recorded in the account, and then the customer purchases U.S. dollars in RMB for repayment after returning to the country. A certain currency conversion fee is generated during this process. Generally, the currency conversion fee is about 1.5 of the transaction amount.

In general, the settlement fees for international credit card online payment channels are mainly due to exchange rate differences, and of course may also involve commissions and other fees charged by the platform.
