1. A portable computerized device comprising: a force detector detecting a near field communication tap; sensors operatively connected to said force detector, said sensors automatically sensing current environmental conditions of a location in response to said near field communication tap; a processor operatively connected to said sensors, said processor automatically calculating a current location-based environmental signature based on said current environmental conditions sensed by said sensors; and a communications device operatively connected to said processor, said communications device automatically matching said current location-based environmental signature to a matching previously stored location-based environmental signature of a plurality of previously stored location-based environmental signatures maintained in a non-transitory computer readable storage medium, said processor and communications device obtaining a machine identification code associated with said matching previously stored location-based environmental signature from said non-transitory computer readable storage medium, and said processor using said machine identification code to process a workflow.
