Under normal circumstances, when we get a new bank card, there is only one basic account in the card, which is a current account. If we want to save the remaining money into a fixed term, in the past, the fixed deposit had to be deposited separately into a fixed deposit passbook. Now the card and fold are integrated, and the bank card can be deposited into a fixed term. In this way, the money must be transferred out of the basic account. Transfer to a fixed-term account. So how should these two households be named? Especially to let the machine know which account to distinguish, then name the basic account 000 account, or
0000, 00000, and the other accounts produced first are called 001, or 0001, This 000 or 001 is the account code.
