ABSTRACT:
The invention disclosed provides a method, system, and tag for detection and tracking of objects. The method includes the steps of: a) attaching to each of the objects a low radio frequency detection tag having an antenna, a transceiver, a data storage device operable to store data including identification data, a programmed data processor, and an energy source; b) storing, in the data storage device of each tag, shipping data; c) commingling the objects in a repository provided with a large loop field antenna; d) reading the identification data and shipping data from the transceiver of each tag by interrogating all tags commingled in said repository with data signals via said field antenna; and e) transmitting the identification data and shipping data from each tag to a central data processor to provide a tally of the objects in said repository.
