A checkbook is a book containing pre-printed checks that individuals or businesses use to make payments. Each check includes spaces for the date, payee, amount, and signature, allowing the account holder to withdraw funds from their bank account. Checkbooks are often linked to a checking account, which provides easy access to funds for everyday transactions. Using a checkbook can help individuals manage their finances by keeping track of spending and maintaining a record of payments. While digital payment methods are becoming more popular, many people still use checkbooks for certain transactions, such as paying bills or making large purchases, due to their convenience and security.
