Overdraft protection from savings helps protect your checking account from insufficient funds charges and “bounced” checks. Should you choose to take advantage of this service, we will transfer funds from your savings account (-0) to your checking account (-900) as needed to cover a check or withdrawal request. The funds transferred will be the exact amount (subject to the available balance in your savings account) necessary to cover your check or withdrawal, leaving your checking account with a $0.00 balance.
