The reason why the item cannot be redeemed may be due to abnormal card status, card swipe limit, card damage or expiration, merchant or POS machine problems, etc.

The credit card cannot be redeemed for the following reasons: : Abnormal credit card status: such as card blocking, risk control, freezing, etc., which may cause the credit card to be unable to be swiped normally. If it is due to risk control or freezing, you can contact the bank customer service in time, explain your consumption situation and identity information, and request to lift the risk control or freezing.

Card swiping limit is set: If a credit card has a transaction limit set, when the amount swiped exceeds this limit, the transaction will be rejected. At this point, you can query and adjust the credit card limit settings.

Card is damaged or expired: The credit card may not be read properly due to degaussing, damage or expiration. Check the magnetic stripe on the card for damage and whether the card has expired. If it is expired or damaged, you should contact the bank promptly to replace the card.

Merchant or POS machine problems: The merchant for transactions may be restricted, or POS machine failure, network problems, etc. may cause card swiping failure. In this case, you can try to change the merchant or POS machine, or swipe the card in a place with a good network environment.

In addition, you should also ensure that you comply with the regulations on the use of credit cards. For example, you are not allowed to transfer or lend a credit card, and you should be fully responsible for payments made with your credit card.

If the above situations are eliminated but the credit card still cannot be swiped out, it is recommended to contact the bank customer service directly or go to the bank counter for consultation and processing. They can provide more specific help and solutions.
