Abstract: A portable viewer for viewing bar codes and other markings printed at least in part with invisible inks includes a light source for illuminating and exciting the ink of the bar code, a camera for detecting light emitted by the excited bar code and for outputting image data, a display for creating a visible image of the bar code from the image data output from the camera, and an optical system for projecting the visible image onto a viewing screen. The display may be a miniature, transmissive active matrix liquid crystal display with high resolution that produces a sharp, bright image. A backlight and lens project the image produced by the display to generate an enlarged virtual image that can be easily viewed by a user. The portable viewer is compact in size and can be accommodated in a small package and requires only a small amount of power.
