After the new card is replaced, the card number and security code will change, so you have to remember to log in to online banking and mobile banking to update the card information, as well as the third-party payment platform that was originally bound to the old card. It is also necessary to update the information in time to avoid repayment failure caused by the old card number during repayment. It's broken when it expires.

When using a new card after the credit card expires or is reported lost, the bill is in arrears, amount, overpayment, points, etc. What's on the old card will be carried over to the new card. Therefore, if the old card has outstanding bills, the cardholder only needs to return the new card within the prescribed repayment period. If the customer can't pay off in full, he can also apply for bill installment or minimum repayment amount.
