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, said processor and communications device obtaining said machine identification code based on said matching said current location-based environmental signature to said matching previously stored location-based environmental signature, and not based on wireless near field communications, to provide near field communications behavior to devices not having near field communications capabilities, and said processor using said machine identification code to process a workflow.
