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 thermal 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 transfer 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 capabilities to manipulate data and accommodate multiple input devices on a single port. Evolving from our beginnings thermal as an electronics distributor, we have grown to become a leading automatic data collection solutions provider. Our reputation for technical transfer proficiency is matched only by our dedication to ensuring complete customer satisfaction. Our knowledgeable sales and thermal support personnel are at your service, delivering solutions to your applications problems. And, as a certified provider for the industry''s leading hardware manufacturers, your system will be installed utilizing state-of-the-art data will collection transfer and RF communications technologies. Our applications expertise encompasses asset tracking, factory data collection, warehouse, all phases of barcode scanning, labeling systems and more. Our company can provide the thermal full range of laser and thermal transfer label supplies for the full range of printers. We provide discount pricing for some popular barcoding printers. We also carry a full line of scanning equipment. The "wand" is the simplest and least expensive input device available. It is durable and contains no moving parts. It must, however, come into contact with the bar code, which can present a challenge. If a bar code must be read more than once, it may become smeared or damaged and, in essence, unreadable. Also, a wand is "human powered," which means it must be held at the transfer proper angle and moved at the proper thermal speed. For these reasons, transfer a wand is the best choice when cost is the largest determining factor. The CCD, or "Charge Couple Device," is another common input device. A CCD is a very "aggressive" instrument, with a high ability to read bar codes quickly and easily. But it has two primary limitations. First, it has a short "read" range, and must be held no more than 1 to 3 inches from the bar code.
