ABSTRACT:
A method and system for providing accurate location of a consumer service device (CSD) in a retail establishment via light modulated by a reflector with a location code. A plurality of location code reflectors (LCRs) are hung from the ceiling of the retail establishment. Each LCR is placed at a preset angle to reflect and modulate a laser beam (or other light source) with a unique location code down to the ground. A laser generation device (LGD) emits a laser beam, which is modulated by the location code when it is reflected off of the LCRs and is reflected to the ground. The modulated laser beam is captured/received by a photo detector/digitizer of the CSD. When the CSD's photo detector/digitizer receives the modulated location code, the location code is utilized to determine an actual physical location of the CSD. The items at that physical location and/or discounts, etc., may be outputted to the consumer.
