A bank account is a financial account maintained by a bank or other financial institution that allows individuals or businesses to deposit and withdraw money. There are different types of bank accounts, including checking accounts for everyday transactions and savings accounts for saving money and earning interest. Opening a bank account typically requires personal identification and an initial deposit. Account holders can manage their funds through various methods, such as online banking, ATMs, and in-person visits to the bank. Bank accounts provide a safe place to store money and facilitate financial transactions.
