Abstract
Tracking devices having computational and communication resources receive information from a plurality of local devices, such as passive RFID tags, and collect and process the received information to determine one or more of when, where, and in what format to forward the collected information. The tracking devices typically include hardware resources for temporal- and location-awareness. In operation, these tracking devices may receive and respond to queries from remotely located tracking entities. In some embodiments, records of the communications between the devices and the remotely located tracking entities are made, and charges for the communication services are billed to the tracking entities that receive the communication services.
