When you close a credit card, it is best to close it. If you just return your card, you won't be able to enjoy the treatment and preferential treatment of new customers the next time you apply for a credit card from the same bank, and canceling your account can avoid this situation.
Extended data:
If the cancelled bank card is inserted into the ATM, the ATM will generally prompt that the credit card is unrecognizable or the account is abnormal, which means that the cardholder can't use the credit card again after 45 days of cancellation, and then the banking system will automatically cancel the account.
Credit cards basically have an annual fee, but they basically have an annual fee-free policy. For example, CCB can be exempted as long as it is brushed three times a year; But if you don't swipe your card to the bank the specified number of times within a year, you need to charge an annual fee. After closing the account, you don't have to pay the annual fee.
After the credit card is cancelled, it should be destroyed in time to prevent unnecessary losses.
