Further, the CCD has a limited width, and will not read bar codes that are wider than the face of the input device. It is largely popular for use in point of sale applications. The laser scanner is perhaps the most popular bar code input device. A laser scanner need not be close to the bar code to do its job. A standard range laser scanner can read a bar code from about 6 to 24 inches away, and a long range scanner can read one from perhaps 2 to 8 feet away. An extra long-range device can even read a bar code 30 feet from the device. Laser scanners vary in price from $200 to $2,000 and come in a variety of models. A decoder may be located inside or outside the input device. An internal decoder takes up less space and is less expensive, but it is also less functional. An external decoder is a bit more expensive, but is also more functional, with the videxscanner capabilities to manipulate data and accommodate multiple input devices on a videxscanner single port. Actually, videxscanner a bar code works in much the same way as an ordinary flashlight -by reading the reflected light from a surface. The process begins when a device videxscanner directs a light beam through a bar code. The device contains a small sensory reading element. 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 bar and are recorded in mils, or 1/1000 inch. A 15 Mill bar code, for instance, has a narrow bar that is 15/1000 inches wide. Further, "quiet zones," or blank spaces to 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 videxscanner convert light energy into electrical energy. There are a variety of input devices, each with its own unique characteristics.
