A bank is defined as a financial institution that accepts deposits from customers and lends and invests those deposits to earn a profit. There are several major types of accounts individuals can open including savings accounts, current accounts, fixed deposits, and recurring deposit accounts. Savings accounts are for individual savings and cannot be opened for business purposes. To open a savings account, individuals must choose a bank, provide know-your-customer documents like ID proof, submit an application form, and maintain a minimum balance. Banks offer varying interest rates on savings accounts depending on the amount deposited. A nominee is a person nominated by the account holder to receive the funds in the event of the holder's death.
