Abstract
A method to wirelessly monitor an entity having an attached transponder is disclosed. A geographical zone is defined. The geographical zone can be defined by allowing a user to define and load to a transponder a plurality of waypoints, each waypoint defined by a geographical coordinate and a radius originating from the geographical coordinate. The geographical zone can also be defined by selecting a plurality of coordinates that are loaded to a transponder and mapped on a pixilated image. The microprocessor in the attached transponder is programmed to determine the occurrence of an event associated with the status of the entity in relation to the geographical zone. The microprocessor in the transponder is also configured to transmit the data related to the occurrence of an event from the attached transponder to a user.
