Credit card merchant staging and shopping mall staging are the same thing. When merchants are in installments, cardholders need to carry the payee's ID card to go to the mall to spend money, and plan to pay by installments. When checking out, you need to verify the identity information of the cardholder. Some banks will have a delivery fee, and the number of installments and the handling fee rate need to be clear. When using the installment business, you only need to apply to the salesperson or telephone at the checkout. The difference between credit card mail order installment and online shopping installment is that if the goods purchased by the cardholder are obtained online, they can order directly online and then apply for installment by telephone, which is called online shopping installment. It's also called mail order installment. After the cardholder purchases goods from the merchants designated by the issuing bank, and provides the issuing bank with information such as goods and payment card number, the cardholder applies for installment payment. Banks generally require customers to fill in the purchase order of credit card installment goods, which will be audited by the bank and mailed to the installment business department of the bank. The cardholder signs for the goods after the application is completed, and repays the arrears in installments according to the credit card statement.
