Overdraft Protection links your eligible Bank of America checking account to another Bank of America account (such as savings, credit card, eligible second checking account or line of credit) and automatically transfers available funds to cover purchases and prevent returned checks and declined items when you don't have enough money in your checking account.

We have a second checking account that's just for bills and a portion of each of our checks automatically goes into it. (allfinancialmatters.com)
For example, let's assume you have three separate accounts at Bank XYZ: a checking account holding $ 10,000, a second checking account holding $ 50,000, and a $ 60,000 CD, for a total of $ 120,000 on deposit. (investinganswers.com)
