Hello, if you use China Merchants Bank's credit card for overseas online payment, after selecting the goods to be paid, enter the credit card number, expiration date and CVV2. You don't need to activate the online payment function in advance and you don't need a password. If you are prompted to enter the VISA or MASTER verification transaction code, you need to enter the credit card inquiry password. When paying through foreign websites, some websites need to pass security verification before the transaction can be successful. It is suggested that VISA/MASTER network authentication service can be opened first.
