Great Wall International Card US Dollar Card is swiped in the UK, and merchants do not charge any fees. But you have hidden expenses in exchange. Expenses incurred: when you swipe your card, the credit card pays pounds for you, but your card is charged in dollars, and the card company conducts real-time transactions to buy pounds in dollars; When you repaid the loan, you made another transaction of buying dollars with RMB, and made two foreign exchange transactions altogether.

Suppose you used a pound card to pay for the same transaction at that time, just charge the pound directly, and RMB repayment is only a foreign exchange transaction.

Compared with the above two transactions, you actually bear about 1%- 1.5% of the foreign exchange fee. This expense is hidden.

If it is a small payment, there is no need to care. However, if it is a large purchase, the Great Wall International Card of China Bank has a pound card, so I suggest you handle it.
