First, the same bank:

1. Operation steps: If the bank card you want to replace belongs to the same bank as the original bound bank card, then: First, you must dissolve the relationship between the original bank card and the bank period, and then bind the bank period with another bank card.

2. Precautions for the dissolution of the bank-period relationship: Take valid identity documents to the bank outlets to dissolve the bank-period relationship (ICBC, CCB, Bank of Communications, China Merchants Bank, China Everbright, Xingye and Bank of China support online banking to terminate the contract, and other banks can only handle it at the counter). Special note: can there be capital flow on the day of processing?

Second, the bank card with silver binding does not belong to the same bank. Choose one of the following two ways:

1, directly bind the new bank card (recommended), just bind the new card directly, the signing method, online banking signing, bank counter signing. Having said that, you may ask: How many bank cards can a futures account bind? The answer is that a futures account can be bound to multiple bank cards.

2. Cancel the banking relationship of the original bank card and bind the new bank card.
