Abstract

Electronic badges are indirectly tracked by detecting, by a badge communicator on a select industrial vehicle of a fleet of industrial vehicles, the presence of an electronic badge and performing a badge logging transaction in response to detecting the electronic badge. The badge logging transaction includes receiving, by the badge communicator, a badge identifier transmitted by the detected electronic badge. The badge logging transaction also includes determining, by the badge communicator, an offset measurement of the electronic badge relative to the select industrial vehicle, electronically determining a vehicle location of the select industrial vehicle, and identifying a badge location based upon the determined vehicle location and the measured offset. The badge logging transaction can also include generating a time stamp, and wirelessly communicating a badge locator message to a remote server, the badge locator message including the badge identifier, the badge location, and the timestamp.
