National Scientific Corporation operates in the Semiconductors and related devices sector. National Scientific Corporation (NSC) is primarily engaged in research, development, manufacture, and sale of hardware and software computer-based products and devices that span a range of industries. The majority of Company's products are mobile computers configured as digital video recording devices with location-determining and tracking capabilities. Its location technologies typically use global positioning system (GPS) technology to determine position. They also use small computers in conjunction with video cameras and other sensors to record incidents on mobile systems, especially school buses. The Company also has other products that use non-GPS technology to establish and then report position. NSC refers to its location-determining devices as its location tracking products, or as location tools products. The Company's primary customer focus for these location-tracking products is the safety market, related in many cases to the safety of school age children.
