The credit card holder needs to provide the card number to the bank, and the bank's backend query can be used to investigate clearly.

It is normal for every bank's credit card to have problems with credit card swiping at every stage. As for the issue of the card swiping limit being continuously reduced, the editor of Jintou Credit Card introduced that the bank credit card swiping limit will be dynamically adjusted according to the card usage. If the credit card consumption limit continues to decrease, cardholders can call Ping An Bank’s customer service hotline to report it. The specific reason can only be known by the staff through background investigation of the consumption records of the card number.

What should I do if my Ping An Credit Card cannot be used? The editor of Jintou Credit Card said that there are many reasons why credit cards cannot be swiped, including problems with POS merchants, lines, and credit card magnetic stripes.
