1. A system for detection and tracking of inanimate and animate objects, said system comprising: a) a low radio frequency tag carried by each of the objects, said tag comprising a tag antenna operable at a low radio frequency not exceeding 1 megahertz, a transceiver operatively connected to said antenna, said transceiver being operable to transmit and receive data signals at said low radio frequency, a data storage device operable to store data comprising identification data for identifying said detection tag, a programmed data processor operable to process data received from said transceiver and said data storage device and to send data to cause said transceiver to emit an identification signal based upon said identification data stored in said data storage device, and an energy source for activating said transceiver and said data processor; b) at least one field antenna disposed at an orientation and within a distance from each object that permits effective communication therewith at said low radio frequency; c) a reader in operative communication with said field antenna, said reader being operable to receive data signals from said low frequency tags; d) a transmitter in operative communication with said field antenna, said transmitter being operable to send data signals to said low frequency tags; and e) a central data processor (e.g. server) in operative communication with said reader and transmitter.
