Is the application filled out online? Or did you go to the branch to fill out the form?
If it is online, it cannot be revoked after the submission is successful. If the bank staff contacts you during the review process, you can ask to stop it. If you are not contacted, or the final card review is passed, you can wait until you receive the card. Apply for card suspension.
If you filled out the form at an outlet, contact the outlet now and request a suspension before the outlet submits your form to the branch.
In fact, you don’t need to do anything during the card application process, so why should you stop it?
And you have received the card. If you don’t need it, you don’t have to activate it. As long as you don’t activate the card, there will be no annual fee. You can activate it at any time when you need to use it. (The card will automatically expire if it is not activated within the validity period and exceeds the validity period)
