You don't have to use the dual-currency credit card of the Bank of China. The dual-currency credit card issued by any domestic bank can pay the SAT registration fee. When paying the SAT registration fee online, use international payment channels, such as VISA or MasterCard, without the online payment function of the credit card itself. The online payment function of China's credit card usually refers to RMB payment, which has nothing to do with international payment channels. Take the international payment channel, generally only need to provide the credit card number and the three-digit CVV number on the back of the credit card, and do not enter the online banking payment interface of the issuing bank.

What I said also applies to the dual-currency card of China Bank. The staff of a branch of China Bank may not have made international payment online, and what he said may be incorrect.

(3) Credit cards generally don't need to be recharged in advance (the correct term is overdraft), but they need to be repaid in advance, but they can be repaid on the repayment date after use.
