Users who change their bank cards without changing their numbers can bring their ID cards and bank cards to the bank outlets. As long as the bank card is not lost, you can change it without changing the number. If you lose your bank card, you can't change it without changing the number. Only the bank card can be reissued. After the bank card is reissued, the card number will change, and the previous business will be automatically transferred to the new card, but the third-party depository accounts, such as stock accounts and futures accounts, need to be re-bound.
