A vertically integrated automobile manufacturer produces its own bumpers. The bumpers are stored on mobile racks until needed by the final assembly line. To migrate from a paper based system to RTLS, a BLE tag was inserted into the traveler pouch on each rack. Backend systems associated the tag with traveler information. Over time, all paper travelers were eliminated. Not only could the inventory of bumpers be managed in real time, but the location of each rack helped deliver the right racks to the assembly line.
