Disclosed are a film (200) having codes recorded thereon, a reader (100) used to recognize the film having the codes recorded thereon, and electronic equipment including a display device to which the film having the codes recorded thereon is attached. The reader includes a light emitting part (110-1) irradiating light having a first wavelength onto a film surface printed with a code by using a predetermined fluorescent material, and a light receiving part receiving only a light having a second wavelength radiated by the predetermined fluorescent material if the light having the first wavelength is irradiated on the code. The reader recognizes the codes together with a screen when a code pattern is printed on the surface of the transparent material and the transparent material is attached on the surface of a display part provided in the electronic equipment.
