Legal analysis: The impact of the cancellation of CCB's credit card is that the parties can no longer apply for the same credit card of CCB, and the cancelled bank card can no longer be used. However, the issuing bank can handle the account cancellation procedures for the parties only if there is no outstanding payment.
