As most of us know, a barcode provides a method of identifying an item for sale through a series of numbers. This data is examined by a computer and matched with the barcode encoded for that item in a database, after which information associated with the product is retrieved and the inventory is updated. No matter the barcode's intended use, the information must be fed into a computer for interpretation, a job reserved for barcode scanners. Make yourself one of the luckiest person who see page
about the barcode scanner.
Basically, the scanner functions like any other input device. First, it forwards data to the computer through a wire and is connected through a port. Scanners mostly use a PS2 or RS-232 port, but more modern models now have USB connections for easier access and installation. This development has also made these scanners more popular than ever. Scanners can cost anywhere from a hundred to several thousands of dollars, depending on the application and the type of technology required. Before purchasing a correct barcode scanner, know that these devices generally run on two types of technologies - image and laser. If you are interested in Intermax

Image based barcode scanners work with the use of a small camera that accepts the barcode as a digital image. After the barcode is scanned, it is entered into a special computer for processing and interpretation. The correlated data that results from this is pulled from a database and updated as necessary for the transaction at hand.
Laser barcode scanners, on the other hand, have more moving parts compared to image scanners and are thus more prone to damage resulting from accidental impact. But while more expensive, these scanners work in far greater distances compared to image scanners and are therefore used in more applications. Laser-based scanners function by reflecting lasers using a set of lenses and mirrors that read the barcode. Like image-based scanners, laser scanners also interpret the data using a computer and do the same steps in terms of updating related data.

The bigger question that is, which scanner must be used for which application? This will dictate the barcode scanner technology that must be used to provide the best result. Laser based barcode scanners are good for stationary environments, especially in factories and manufacturing facilities where long scanning distances are required. If a scanner is to be used in a close-quartered or extreme environments, like in the outdoors or in environments where the weather is extreme, it is often wise to use the barcode scanner because of its durability.
