Opening a card means activating the card, usually activating the credit card. After the credit card application is successful, it needs to be activated before the card can be used for credit card consumption. To open a card, you can go to a local bank branch, call the customer service number, or go through online banking. It should be noted that some banks stipulate that annual fees will be charged even if the card is not opened. It is recommended that cardholders pay attention to the annual fee of the credit card they apply for to avoid overdue records.
