Hello, you can report the loss by phone, or you can bring your valid ID card to the counter outlets to report the loss. It is suggested to choose the first method here, which can save the time of going to the bank in person. After reporting the loss, the credit card will be in the state of stopping payment, and the new card can not be used until it is activated. At the same time, the old card will be officially invalid, and information such as the balance, account and limit of the old card will be loaded on the new card. The password is the same as the old card. If you feel uneasy, you can modify it.
