First, when you cancel a credit card, you must make sure that there is no debt in the card. This debt includes not only visible account debt, but also annual fee, interest and value-added service fee. Otherwise, debt may still arise after card withdrawal, so users must consult the bank clearly when returning the card. If there is a balance in the credit card, you can't take it out, because taking it out may also generate handling fees and interest. Users should first consult the corresponding bank's credit card withdrawal and cancellation fees before deciding to cancel the card. Credit card sales are generally handled through telephone banking. Ask the customer to provide detailed information for verification, but telephone handling is not the right time to close the account.
Second, for credit cards that have been cancelled, users can't throw things away. Because if the card face is complete, such a card can still be used in some consumer places that only need to provide the card number without checking information. Therefore, after the user logs off, he must cut the magnetic stripe and cut the card into pieces to prevent criminals from stealing.
