After the credit card expires, as long as the cardholder meets the conditions for issuing a new credit card, the issuing bank will mail the new credit card to the cardholder before the credit card expires. After the new credit card is successfully activated, the old credit card will be invalid. At the same time, all business on the old credit card will be transferred to the new credit card. The business content of the new credit card is the same except the card number and expiration date.
