Overdraft Protection Service 

Overdraft Protection Service (OPS) provides overdraft protection to customers that maintain both a checking and savings account. In the event your checking account becomes overdrawn, the exact dollar amount is automatically transferred from your savings account to your checking account. If sufficient funds are not available in your savings account, normal overdraft fees will apply to your checking account.
