Hello, the credit card of China Merchants Bank will be repaid in US dollars. There are three ways for your reference (except full currency card): 1. All-in-one-card and credit card have self-service transfer function at the counter. All-in-one-card directly purchases foreign exchange in US dollars, and online banking directly repays it manually. 2. If it is inconvenient to go to the counter, a credit card will be opened, and the credit card will be automatically debited after purchasing US dollars. 3. The credit card has the function of purchasing foreign exchange, and the one-card card is also RMB.

If you choose the third method, you need to activate the foreign exchange purchase function. Just log in to online banking in Repayment Management-RMB Automatic Foreign Exchange Purchase and activate the function. There will be some instructions on the operation of online banking. Please refer to it in detail.

Inconvenient full repayment has two ways for you to choose:

1. Billing installment (only for business cards, business cards (including financial business cards), purchase cards, ANA protection cards or supplementary cards): you can enjoy the interest-free period, but there is a handling fee. Handling fee per installment = total installment amount × handling fee rate per installment. The minimum handling fee for each period is 5 yuan, and the benchmark rates for each period are: 0.9% for the third period, 0.75% for the sixth period, 0.70% for 10, 0.66% for 12 and 0.68% for 18 respectively. Then the repayment amount of each installment is 800/6= 133.33 yuan, and the interest of each installment is 800*0.75%=6 yuan) For details, please log on to the credit card website/and click "Credit Management"-"Bill Installment" to inquire; It's really impossible to get cash in installments.

2. Minimum repayment amount: no handling fee but no interest-free period. If the minimum repayment amount is paid before the final repayment date, but less than the full amount, you cannot enjoy the interest-free repayment period. From the bookkeeping date (usually the day after consumption), interest will be charged on all consumption in the current period, with a daily interest rate of 0.5 ‰ until you pay it off in full.
