Generally, when swiping a card overseas, if the transaction is not directly recorded in RMB, many banks will enter the US dollar bill at the exchange rate on the trading day, and the exchange rate on the billing day will be converted into RMB.

the calculation of exchange rate when swiping a card abroad is related to the card organization and the issuing bank, because the exchange rate will be different if the card organization is different, and the exchange rate will be different if the issuing bank is different, and the calculation methods of possible exchange rates are different for different issuing banks, and sometimes there will be currency conversion fees for swiping a card.

the exchange rate calculation of unionpay standard card is the simplest among all credit cards. when unionpay cards are swiped abroad, unionpay will convert the local currency we consume into RMB according to its own exchange rate. The exchange rate of UnionPay is not good, but the currency conversion fee is exempted.

for example, if you swipe $1, on the 1st of the current month, you will be billed in US dollars at the exchange rate on the 1st, and if the 21st is the billing date of this card, you will convert US dollars into RMB at the exchange rate on that day. Or some banks directly bill in dollars, then the exchange rate on the repayment date shall prevail.

Therefore, if the exchange rate of the US dollar keeps rising, it is suggested to repay the bill as soon as possible, otherwise, it can be repaid before the final repayment date.
