The reasons leading to the failure of credit card transaction may include: online payment is not enabled, the network is unstable during the transaction, the transaction is not authorized, the amount of a single transaction exceeds the limit, the credit card is in an overdue state, and the user is suspected of stealing or cashing out. Because there are many reasons why credit card transactions fail, after the first transaction fails, users can try to change to a POS machine for credit card consumption.

If the POS machine has not been swiped successfully, then the card itself may have caused the transaction failure.

Credit card degaussing. Credit cards can only be used through the magnetic stripe on the card. If the magnetic stripe is degaussed or damaged, the credit card will not be used normally. At this time, the cardholder needs to contact the issuing bank in time to change the card.

Overdue repayment is frozen. When the cardholder uses the credit card, it is often overdue and the bill has not been paid off for a long time. At this time, in order to avoid the capital risk, the bank will control the risk of the card, resulting in the freezing of the credit card. If the credit card is frozen, the cardholder will prompt that the transaction failed when spending by swiping the card. If you want to continue to use the credit card, you need to pay off the arrears and apply for thawing.

Consequences of overdue credit cards

1, you will leave a court enforcement record on the central bank's credit record.

So, dear customers, you are also young people. It is almost impossible to get credit cards and loans from banks, financial institutions or small loan companies in the future.

2. You will become a credit blacklist.

In the future, if you take the high-speed train and the ash machine, your children will be affected by your malicious overdue. Then you lose not only things related to money, but also your family, your love, your friendship and even your most basic feelings.

Payment password entered incorrectly. As we all know, in the process of credit card transaction, if you enter the wrong password three times, the credit card will be automatically locked. In this case, credit card consumption must be an abnormal transaction. If normal transactions are to be resumed, cardholders need to bring their ID cards to the bank to change their passwords and unfreeze them.

Credit cards are at risk of being stolen. Credit cards have always suggested that the transaction failure may be caused by abnormal transactions. The credit card application platform detects that the cardholder's credit card is at risk of being stolen by others, and the bank will freeze the credit card in order to avoid or reduce the cardholder's financial loss. If this is the case, the cardholder only needs to explain it clearly to the bank. If it is stolen, you need to call the police in time.
