Systems which comprise an automated transaction machine which includes one or more customer interacting means such as, in the case of an integrated circuit card terminal, at least an integrated circuit card reader; infrared communication emitters and individual short range infrared communication emitters located in the machine. The emitters are adapted to provide repeating, directionally sensitive frequency modulated message signals identifying the direction to and location of the machine. Thus, a person having a portable receiver for such signals is led to the machine and is able to position himself/herself in front of the machine in order to operate it. The respective emitters provide separate repeating, directionally sensitive frequency modulated message signal which identifies the location of the respective customer interface on the machine so that by movement of the portable receiver in front of the machine, the location on the machine of the respective customer interfaces can be determined. Instructions on use and/or feedback concerning transactions can also be provided from the system to the customer through the portable receiver. The signal transmitters may also be adapted for highly efficient use in the presence of a wide range of levels of ambient light energy, e.g., sunlight. |
