1. A joint account refers to an individual current settlement account or lump-sum time deposit account in local and foreign currencies opened by more than two (less than five) individual customers, with no limit on deposits.

2. The traditional personal account only needs the signature and seal of the account holder, and the funds in the account can be withdrawn for transfer and settlement. Individual joint accounts are subject to the terms of signature when used. The so-called signature clause refers to the clause that the depositor of a joint account has the right to sign and seal with the joint account holder when opening a joint account. In fact, it is the rule that the joint account holder agrees to use and control the joint account. As a financial intermediary, banks manage joint accounts in strict accordance with the signature and seal authority determined in the signature terms.
