Credit card overseas online payment generally requires the card number, the validity period of the card and the last three digits of the seven-digit signature column on the back of the card. Some overseas shopping websites need visa verification service or master verification service for online payment. This function can be opened in the online banking of China Merchants Bank.

Overseas online payment generally does not need to enter a password, nor does it need to open the online payment function. If you are prompted to enter the VISA or MasterCard verification transaction code, you can enter the credit card inquiry password.

If you want to buy from the sea, credit cards with the logo of the international credit card organization (MASTER/VISA/AE, etc. ) and dual-currency settlement functions are necessary. At present, there are also a few overseas shopping websites that accept some domestic UnionPay single currency credit cards. Please consult overseas shopping websites for details.
