At present, most credit cards implement a "dual exchange rate" when swiping cards abroad, that is, the local currency must be converted into U.S. dollars first, and then the U.S. dollars must be converted into RMB. This exchange process will actually produce Additional exchange losses.

When the consumption amount is large, the currency conversion fee will also be high. When spending overseas, there are two types of credit cards that can waive currency exchange fees. One is a credit card in local currency, and the other is a UnionPay card. The former only handles very few travel applications, while the latter requires more handling, but you need to consult customer service and consider the popularity of UnionPay transaction equipment in tourist destinations.

Recently, there are also credit cards that record accounts directly in RMB and repay in RMB, thus avoiding unnecessary exchange rate losses.
