The main difference between the new card and the old card is that the validity period of the card is different from CVV2 code, and the card amount, card level and card number are the same. Because the card numbers of credit cards are the same, when the user's old card is bound to the third-party payment software, as long as the new card is activated, it can continue to be used, and the validity period will be calculated according to the new card.

Of course, if the user wants to change the card number or upgrade the card, then he needs to apply for a new card again, and there is a certain chance that the new card application will not pass the examination.
