Many banks have a drive-through automated teller machine, built into the wall flanking the driver' s side of a narrow aisle
Even though blind people obviously do not drive, these machines nonetheless invariably feature Braille -- the system of raised dots used by the blind for reading and writing -- in addition to the standard letters and numerals on their control panels
The embossing technique used to form the raised dots does not typically add much to the overall cost of the automated teller machine.
