second, what is the impact of changing credit cards? According to the reasons for card replacement, the impact is different. Common reasons for card replacement include card replacement due to loss of report, card replacement due to damage, etc. The specific impact is as follows: 1. Card replacement due to loss of report: after the loss of report, the old card can not be used except for repayment. After the loss of report is successful, the bank will issue a new card, and the new card number is different from the old card. After the new card is activated, the old card will be invalid, and the accounting information of the old card can be transferred to the new card. 2. Change the card if it is damaged: you can't use the card after the credit card is damaged. The bank will reissue the new card, and the account number of the new card is the same as that of the old card. Just repay it directly to the old card account. 3. Card replacement upon expiration: The bank usually sends a new card one month before the validity period of the credit card, and the new card number remains unchanged. After activation, the old card becomes invalid, but it can still be repaid directly to the old card account. The above is the introduction of "Does credit card change affect repayment?" I hope it will help everyone. In short, credit card replacement will not affect repayment, and everyone can return the money to the old Kaka number as usual. If you really don't know the impact of changing your credit card, you can call the customer service phone of the issuing bank to consult the customer service.
