How can I exchange dollars in my credit card for a trip to Europe?

First, if you have a dual-currency credit card with US dollars, you can use VISA or MasterCard to swipe your card, swipe your local currency in Europe, and convert it into US dollars according to the DCC dynamic exchange rate, and charge a certain exchange fee.

Second, holding a dual-currency card of RMB and Euro, you can swipe the Euro and directly input the Euro, and there is no limit to conversion.

Third, if you hold a multi-currency or all-currency credit card, you can automatically convert it into RMB by swiping euros. At present, most banks are exempt from the exchange fee for multi-currency credit cards, which is more cost-effective than the US dollar dual-currency card.
