Don't turn it out. The bound bank card can be added or modified to the futures account. A futures account can support up to five different bank card bindings at the same time (each bank can bind up to 1 bank card). When adding or modifying the bound bank cards, the futures party does not need any operation (the access rights of five bank cards are released by default), and the futures investors only need to operate on the bank card online banking that needs to be added or modified.
