Overdraft protection

Overdraft protection is a service that automatically transfers funds from one bank account to another in order to avoid overdraft fees when insufficient funds are available. It can apply to savings accounts, checking accounts, lines of credit or credit cards. Overdraft protection carries its own fees, however. Usually, the service is automatically applied when an account is opened and the customer must opt out; other times consumers must sign up for the service.
