Credit cards (debit cards) will not be automatically cancelled, whether you activate them or not.

As long as your credit card (debit card) is successfully processed, it will be recorded in your credit record. If you activate but don't use it, you will pay an annual fee every year. If you don't pay, there will be arrears, which will affect your credit history.

Users are advised to cancel unused credit cards in the bank to keep a good personal credit record.
