Do you want to ask the question "How does the China Construction Bank app display an incorrect credit card number?" This situation is due to input errors, abnormal card status, system problems and non-updated information.

1. Input error: Please ensure that the card number entered is exactly the same as the card number on your credit card, including all numbers and letters.

2. Abnormal card status: If your credit card has expired, been canceled, or has other abnormal status, the card number may not be recognized.

3. System problems: Occasionally, there may be system problems in the bank app itself, which may cause the credit card number to be unable to be recognized and processed properly.

4. Information not updated: If you have recently changed your credit card but have not updated your card information on the China Construction Bank app, the app may still display the old card number, which is inconsistent with the actual card number.
