Is it cost-effective to travel to Germany by credit card or cash?

it's good to swipe your card when traveling abroad. Because the exchange rate settlement of international credit cards is based on the exchange rate of foreign exchange purchased by international credit card organizations, it is more favorable than the exchange rate used by individuals to purchase foreign exchange. Therefore, credit card consumption is more economical than personal purchase of foreign exchange and then payment. In some places in Europe, you can only swipe your card without accepting cash, but you can only give cash for tips and other things, but you can't swipe your card. Therefore, it is recommended to bring two cards and some cash, and the denomination should not be too large. Of course, if you can swipe your card when you buy something, of course, you can swipe your card, at least you can take less cash abroad.
