Credit card spending rush means that a transaction has been marked as successful at the terminal, but the account transaction package sent to the host computer has not received a response, that is, the terminal transaction has timed out. Therefore, it is uncertain whether the transaction has been successfully completed on the host. In order to ensure the interests of users, the terminal sends a request to the host again, requesting to cancel the transaction process. If the host successfully completes the transaction, the transaction is rolled back, otherwise it is not processed, and then the processing result is returned to the terminal. There are two results: (1) "reversal succeeded": the transaction gold was successfully returned, and it needs to be swiped again;

(2) "Reversal is unsuccessful": Due to the failure of the POS machine and UnionPay settlement center in the data transmission process, the account of the transaction initiator has been deducted, and the transaction initiator needs to swipe the card again.

The method for judging "successful flushing" and "unsuccessful flushing": 1. Someone swiped the card to spend money, and the mistake was corrected during the transaction, and the shopping list was not printed. The cardholder said that he had received a debit message from the bank. The merchant calls the customer service hotline in time, and the customer service tells the record to check with the bank and reply the next day.

After bank reconciliation, the transaction is "successful" and the transaction will be returned to the cardholder's bank card.

If the merchant has delivered the goods/services: the merchant fills in the Application Form for Receiving and Paying Special Merchants, seals it and submits it to the maintenance worker to apply for payment to the merchant's account;

2. After bank reconciliation, the transaction reversal fails, and the transaction can be returned to the merchant or cardholder. If the merchant has delivered the goods/services, the merchant shall fill in the Application Form for Payment and Receipt of Special Merchants, seal it and submit it to the maintenance worker to apply for payment to the merchant's account; If the merchant fails to deliver the goods/services, please contact the maintenance worker and the money will be directly refunded to the cardholder.
