China Merchants Bank's mobile app can be used to manage card information, including inquiring about the balance in the card, transaction records and applying for temporary quota. If the card information in the mobile app is not updated after the new card is activated, you can try the following steps to solve the problem:
1. Log in to China Merchants Bank Mobile app and enter the "My Bank" or "Card Management" page.
2. Find the card information that needs to be updated in the page, and click "Update Card Information" or "Add Card".
3. According to the page prompts, enter the card number, expiration date and other information of the new card to complete the update of the card information.
If the above steps can't solve the problem, you can try to contact the customer service hotline of China Merchants Bank at 95555. Customer service staff will provide you with detailed help and guidance. At the same time, in order to ensure the security of the card information, it is recommended that you do not tell others the card number of the new card, so as to avoid the loss caused by the leakage of the card information.
