Our interactive teller machines serve as ATM's as well, so we created a sign that is attached to the right of the screen and card reader. We put some bulleted information about check cashing limits, no coin, no cashier's check sales, etc, then the cutoff times for the ITM (teller assisted) transactions and the ATM card access transactions as they are two different times. Then we have the FDIC sign and the Fee sign for the ATM. Some may say it is more than required, but it works as one sign attached to the machine.
