description The present invention relates to low power electronic tags and tag tracking systems. More particularly, the present invention relates to radiofrequency tags externally triggered by a directed light or electromagnetic pulse. A system for identification and tracking of tags distributed in a room, wherein the system includes an electromagnetic pulse generator to produce a local electromagnetic spike, a tag reactive to the local electromagnetic spike to provide a data signal, a data receiver for receiving the data signal, and a tag tracking system receiving input from the electromagnetic pulse generator and the data receiver, the tag tracking system storing state records of position and informational content of the tag.
