Credit card can be used when online banking is opened and the seller supports credit card payment. The payment steps are as follows:

Step 1: The buyer selects the goods he wants to buy in the online shop (click "Add to Shopping Cart" to add the selected goods to the shopping cart).

Step 2: Check the detailed information of the purchased goods in the shopping cart (click "checkout" to pay for the purchased goods).

Step 3: Select the courier type (after selecting the courier type, click "Continue" and then select the payment method).

Step 4: Choose the payment method (choose credit card payment).

Step 5: Order confirmation (make final confirmation, and then click "Submit Order" to enter the payment gateway page for credit card payment)

Step 6: Enter the credit card payment page, and the buyer fills in his credit card information (after filling in the relevant credit card information, click "Pay", and the system will automatically encrypt the credit card information, order amount and order number and send them to the bank for verification).

Step 7: Return the payment result (the serial number formed by the website and the payment result seen by the buyer).

Step 8: The merchant can see the payment of this order in the background of the paying merchant. If the payment is successful, the merchant can deliver the goods to the buyer.
