A bank check is a written order directing a bank to pay a specific amount of money from the account of the person who wrote the check, known as the check writer, to the person or entity named on the check, called the payee. Checks typically include details such as the date, amount, and signatures, ensuring they are valid and can be processed by the bank. When a check is deposited, the bank verifies the check writer's account to ensure sufficient funds are available. Once confirmed, the bank transfers the specified amount to the payee's account. Checks are commonly used for payments, as they provide a secure method of transferring money without cash.
