It has become a trend to change the core of bank cards and credit cards. At present, banks are also vigorously popularizing financial chip cards. After replacing the core, it should be noted that:

1. If the original magnetic stripe card is a salary card, replace it with a new financial ic card. If the original card number cannot be maintained, I need to apply to the financial department of the unit for changing the salary account.

2. If the original magnetic stripe card was previously bound with a loan-related repayment account, it is recommended not to change the magnetic stripe card into a financial ic card, in case the bank cannot change the card number, because the loan repayment account belongs to the designated account. If it is changed, the procedure will be troublesome, and problems will affect the normal repayment and personal credit history.

3. If the original magnetic stripe card is previously bound with investment accounts such as wealth management and funds, the change is relatively simple for the cardholder, and the account can be changed by transfer, but it is forbidden to wait until the investment expires. If it is changed in advance, it may have an impact on the return of funds.
