A checking account is a type of bank account that makes it really easy to access your money.
As long as you have money in your checking account, you can get cash from an ATM, use your debit card to buy stuff, or write checks. Even though a checking account is the easiest way to take out money, the downside is that a checking account usually has a lower interest rate than a savings account or other places you can store your cash.
A check is a note that is issued from one entity (like a person or business) to another for the purpose of transferring money. The check itself is a piece of paper that represents deposited money in the check-writer’s bank account, that is to be paid out when the check is “cashed” or deposited by the recipient. A checking account gets its name from the fact that funds may be transferred from the checking account to another account using checks.
