1. One of the reasons why the credit card transaction amount exceeds the limit may be that the cardholder has set a limit for single or cumulative consumption on the same day, and credit card consumption cannot be made beyond the limit.

2. If the cardholder's credit card is improperly used or there is a risk of theft, the bank will control the risk of the cardholder and limit the transaction amount.

3. If the cardholder's credit card limit is insufficient, the transaction amount will also exceed the limit.

What if the credit card transaction amount exceeds the limit? There are several ways to cancel the over-limit transaction:

1. If the credit card transaction amount is set by the cardholder, you can reset it yourself, or you can go to the bank counter and ask the staff to help set the transaction limit.

2. Cardholders can improve their personal online banking information and call the bank's customer service phone to apply for large consumption.

3. Cardholders need to use credit cards normally for a period of time, and their consumption is diversified. After the bank monitors that the cardholder meets the conditions of large consumption, it will automatically cancel the credit card transaction amount limit.

4. If the credit card limit is insufficient, the cardholder can pay off the outstanding amount of the credit card and restore the credit card limit after paying off; If the original limit is still insufficient, the cardholder can apply for withdrawal.
