Also referred to as "Overdraft Transfer Protection", a checking account can be linked to another account, such as a savings account, credit card, or line of credit. Once the link is established, when an item is presented to the checking account that would result in an overdraft, funds are transferred from the linked account to cover the overdraft. A nominal fee is usually charged for each overdraft transfer, and if the linked account is a credit card or other line of credit, the consumer may be required to pay interest under the terms of that account.
