After the credit card expires, the original card will automatically expire, and the bank will issue a new card to the user before the expiration. After the new card is activated, the original card will be invalid immediately. Or the original card will automatically expire after expiration, regardless of whether the new card is activated or not. Therefore, expired credit cards can no longer be swiped. Users can only use the credit card within the validity period. When it expires, it will be automatically invalidated, so they can't use it any more.
