I took three credit cards when I went abroad, so it doesn't matter how many I swiped, as long as you can return them. If they don't arrive in a month, they will be paid in installments. Why do you want to deposit foreign currency in it? Visa or master's credit cards are all directly swiped out in foreign currency. When you return them, the bank will convert them into RMB arrears for you to repay. You don't have to worry about this ~ ~
