Because in online banking, you still need to associate the new card. If the card has been linked to online banking after changing, you need to select the new card in the fund account (find the new card in the drop-down menu of specifying or setting the fund account). Otherwise, the information corresponding to the old card in online banking cannot be queried.

If the new card is not associated with online banking after changing the card, depending on the bank, you may need to go to the counter of the bank or the bank where you opened the account to specifically associate the new card with online banking.

Once the setting is successful, the new card information will appear in the fund account of online banking, and transactions can be queried normally.
