the payment method of credit card is mainly that the acquirer submits the payment. The acquirer will deduct a certain handling fee when paying the special merchants, and then make a payment request to the issuing bank. If the issuing bank has no objection to the transaction, it will pay the money to the acquiring bank and share the service fee with the acquiring bank through withholding. Otherwise, it will enter the stage of refusing to pay or re-requesting money, and even finally it will be submitted to a higher-level organization for adjudication.
