  • Patent number: 9129198
    Abstract: Disclosed herein are an information code and an information code reader. In information code, a plurality of light-colored modules exhibiting the reflective characteristics of light color when light of a second wavelength band different from light of a first wavelength band is radiated and a plurality of dark-colored modules exhibiting the reflective characteristics of dark color when the light of a second wavelength band is radiated are arranged in a code region. The information code includes a masked portion disposed in a predetermined region of the code region in which light is intercepted and prevents the corresponding information code from being read, and configured to, when the light of a second wavelength band is radiated, allow light reflected from the modules of the corresponding code region to pass therethrough and thereby interrupt the light of a first wavelength band.
