Hello, after spending US dollars by swiping your card, the limit reduction is calculated based on a fixed 6.35, but the actual repayment amount will be different. Since the exchange rate fluctuates up and down every day, our bank's current exchange rate for foreign exchange purchase and repayment shall be based on the exchange rate announced by our bank at 10 a.m. on the day of repayment for the selling price of US dollar banknotes. Therefore, this reduced amount is not equal to the actual amount that needs to be repaid. This is the particularity of US dollar bills.
