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.

For credit cards that have been cancelled, users are not allowed to throw things. 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.
