A method and system for calibrating a test system and a vector network analyzer use models of unknown calibration standards for a standards-based calibration. A reflection type semiconductor display device according to the present invention can take in light other than incident light on a liquid crystal panel to be an auxiliary light source using optical fibers, and thus, display of high quality level can be made even indoors or in a place where light is faint. Other embodiments of the invention are directed toward heat management, and other process enhancements for making the system especially efficient. A determination is made as to whether to grant authorization based on whether the generated alphanumeric string matches an alphanumeric user identifier stored in a memory device in association with a user.
