This is mainly because if the cardholder makes a manual card pressing transaction before closing the account, the cardholder will have closed the account before the merchant submits the card pressing form to the bank for entry, and the bank cannot settle the account normally.
On the other hand, if the cardholder is in consumption abroad or withdraws cash, it may take several days to settle the account. If the account is closed immediately, it will also affect the normal liquidation of the bank.

Credit card cancellation:
If you don't intend to continue using credit cards, you must do so. If the account is not closed, the bank will charge an annual fee for the credit card.
If the card is not overdrawn, you can apply for account cancellation at any time.
If your card has not expired, you need to apply first, and then go to the bank to cancel your account after a certain period of time;
If the card has expired and the account balance is zero, you can directly cancel the account at the designated bank outlet.
When closing the account, you should bring your valid ID card and the original card. If it's not convenient for me to close the account, someone else can help you. The agent must hold the power of attorney written by the principal (himself) and bring the original valid identity certificate to handle the account cancellation business.
