A checking account is a deposit account opened with a bank that allows numerous withdrawals and unlimited deposits. Current accounts are the most liquid accounts and can be conveniently accessed at any time via ATMs, checks, online banking, and credit or debit cards. Because of these properties, checking accounts are also known as demand or transaction accounts. Various types of checking accounts have been developed to meet user needs, including student accounts, business accounts, and household accounts. Current accounts usually do not offer any interest due to their liquidity.
