Actually, a bar code works in much the same way as an ordinary flashlight -by reading the reflected light from a surface. codes The process begins when a device directs a light scan beam through a bar code. The device contains a small sensory reading codes element. scan This sensor detects the light being reflected back from the bar code, and converts light energy into electrical energy. The result is an electrical signal that can be converted into data. Bar codes are measured by the width of the narrow codes bar and are recorded in mils, or 1/1000 inch. A 15 Mill bar code, for instance, has a narrow scan bar that is 15/1000 inches wide. Further, "quiet zones," or blank spaces to codes the left and right of bar code symbols, are included to insure the bar code can be read. It''s a three-step process. First, an input device must convert light energy into electrical energy. There are a variety of input devices, each with its own unique characteristics.
