Method and system to control movable entities

A method to wirelessly control an entity having a transponder, comprising:

• defining a geographical zone using a plurality of waypoints, wherein each waypoint is defined by a geographical coordinate and a radius originating from the geographical coordinate;
• loading from a computing device to a transponder's memory a plurality of waypoints;
• and
• sending a command to the transponder to execute a configurable operation upon receiving a command from a control center, the command being associated with a status of the entity in relation to the geographical zone.

A method to wirelessly communicate with an entity having transponder, comprising:

• using a computing device to identify a geometrical area using at least two coordinate attributes, wherein said geometrical area is divided into a grid having at least one section;
• defining a geographical zone by selecting within the grid one or more of the at least one section representative of a desired area and correlating the at least one section to a pixilated computer image by associating the at least one section with a pixel;
• loading said pixilated computer image into a transponder's memory;
• and
• programming a microprocessor in the transponder to execute a configurable operation upon receiving a command from a control center, the command being associated with a status of the entity in relation to the geographical zone.

A method to wirelessly communicate with an entity having a transponder, comprising:

• loading from a computing device to the transponder's memory a plurality of coordinates;
• programming a microprocessor in the transponder to define a geographical zone by creating an area using said plurality of coordinates, wherein said area is representative of a geographical zone;
• and
• sending a command to the transponder to execute a configurable operation upon receiving a command from a control center, the command being associated with the location of the entity in relation to the geographical zone.
