It can still be used for the time being. If you receive a short message from CCB reminding you of abnormal transactions, you should pay attention. It may be that the card is often swiped at the same merchant or merchants before use, and almost all the credits on the card are swiped at one time, and then returned next month, and then swiped like this.

In this way, banks may perceive that this method of swiping cards is risky and suspect that it is not a daily personal consumption behavior and is used abnormally. If you still use it as usual, this time it's just a reminder, and it's likely to reduce the card limit or freeze the card next time.

Extended data

There are generally the following reasons for the abnormal display of credit cards.

1, brush theft risk

When your transaction is recognized as risky by the bank and may be stolen, the card will display abnormality. After that, the bank will call to check whether it is my consumption, and if it is, it will be fine.

2. Freeze or report the loss

Frozen cards or loss reporting cards will also show abnormal status. In this case, you only need to find customer service to unfreeze it, and you need to report the loss of your credit card.
