Originally formed to develop radio frequency identification technologies, HID Global was formed in 1991 as Hughes Identification Devices, a subsidiary of Hughes Aircraft Company with offices in California and Scotland. The original 125-kilohertz proximity technology had been pioneered by Destron IDI, Boulder, Colorado and used in many applications including Animal Identification, Tyre tracking and in motor vehicle and aircraft industries to track parts, and the company’s founders thought there would be markets interested in using this technology for other purposes.
