Abstract
A device, system, and method for determining a location of micro digital signage devices includes generating and transmitting a unique identifier corresponding to each micro digital signage device. Each micro digital signage device is to display its corresponding unique identifier and capture an image of other micro digital signage devices located on an opposite side of an aisle. The captured images are to be stitched together to generate a composite image. The unique identifiers of the micro digital signage devices are to be identified and the location of each micro digital signage device is to be determined using a known location of one of the micro digital signage devices as a reference. Each micro digital signage device identified from the composite image is to clear its corresponding unique identifier from display.
