At present, most of the credit cards issued are dual-currency credit cards in RMB and USD, and a few banks have issued all-currency international credit cards with chips. People use dual-currency credit cards abroad. At the time of settlement, the card issuer will convert the local currency consumed by the cardholder into US dollars for bookkeeping (if the local currency is US dollars, it will be directly credited to the US dollar account). When you return home, you need to use RMB to buy dollars at the exchange rate of the day for repayment. However, if people use all-currency credit cards, in consumption abroad, the card issuer will give the bank a preferential price to be credited to the RMB account at the time of settlement, and repay the loan at this preferential price after returning home. Some card issuers not only reduced or exempted 1.5% currency exchange fee for domestic all-currency credit card holders, but also gave 5% cash back to cardholders who swiped their cards to a certain number and amount.

Industry insiders suggest that people who plan to travel abroad had better apply for full-currency credit cards, which will be more cost-effective. For those who have already used the dual-currency credit card to overdraw their consumption, if the foreign currency exchange rate is expected to strengthen, prepayment can reduce the expenditure on foreign currency exchange.
