A barcode scanner is a piece of hardware used for interpreting information and data stored within a barcode. Barcode scanners use lasers, light or imaging technology to read barcode labels printed on products or other items, and then translate and log the details stored within the barcode onto tracking software running on a connected computer. The connection between the barcode scanners and the computer may be made either using an usb/ps2 cable, or using cordless wireless or bluetooth technology.

Barcode scanners have many uses, and are used in a wide range of fields. Their most common and well known use is for recording sales and tracking stock in a retail environment, but barcode scanners are also frequently used for monitoring ticket entry at public events, logging book loans in libraries, tracking the movement of goods shipments, and for many other diverse purposes. The reason barcode technology is used so widely is due to the ability of barcode scanners to read and store information quickly and efficiently at a relatively low cost.

Because of this wide range of uses, barcode scanners come in many shapes and forms, each suited to a particular purpose. This includes handheld barcode scanners (ideal for inventory logging), fixed mount scanners (commonly used for supermarket checkout counters), small pen-shaped barcode scanners and wearable barcode scanners (handy at events where you need both hands free). Whichever model is suitable for you, barcode scanners are reliable, easy to use and available in a variety of price ranges.
