I have not noticed nor have seen one at the Vystar Bank ATM lane...but will remmy to check next time I go....and have no clue as to why they would have it, as drivers are not blind (at least I hope not). But could undy one at the Bank which do have some ATM's out front, as some blind people could walk up and use the Braille pad....
Or be a backseat passenger! Also, some things are cheaper to make one model for several uses. Possible in this case for both walk-up and drive-up.
