Bank card swiping failed to receive SMS.

Hello, the POS machine did not issue a receipt after the merchant swiped the card, but the cardholder received a debit message. In this case, please don't be confused and flustered. This is a unilateral statement. Please press the following solution:

I. Operating the "Reprint" function with the pos machine Purpose: To check whether the purchase order printer is faulty;

Second, trade with any bank card and check the balance. Pay attention to whether there is a word "charging center" on the pos screen, and MIS will observe the password keyboard. If the screen shows that the charging center is successful, the cardholder will receive a refund message soon (UnionPay pos has the charging center function, but the charging center function will only be activated automatically in the next online transaction).

3. What if the cardholder calls the issuing bank and the issuing bank says that the transaction has been successful, and we call the payment service provider to say that it has not been successful? I don't believe you and you don't believe me. You can only check it the next day. The transaction status will be clear the next day, and neither the bank nor UnionPay can see it that day.

Fourth, in fact, the best method is a writing brush. The more you explain to the cardholder, the more the cardholder feels that there is a problem, and directly say that the pen was not successful. If necessary, we can write a note to the merchant, which generally means that if it is found to be overshooted the next day, we will guarantee the return.
