A method and system for controlling use of software and hardware, and for controlling access to and usability of commodities, by use of position (or location) dependent signals emanating from GPS, DPGS, GLONASS, and other sources, in conjunction with time and ephemeris data, wherein the receipt of position (or location) data is verified by reference to independent time and satellite ephemeris data, and where when position (or location) is established within preloaded boundaries, the system is rendered useful. A module which includes software and/or hardware modules (implemented as chip sets in combination with mechanical actuators), and a position (or location) determining system such as a global positioning receiver, built into each device and/or shipping container used to transport devices and/or commodities for control.
