Barcode Readers

A barcode scanner is a device designed to read barcodes printed on a retailer’s products for the purpose of stock control and to recover the latest pricing. They are also known as barcode readers and they are electronic devices that have a light source and a light sensor, used for translating the optical image of the printed barcode into an electrical image. The electrical information can be linked to an electronic till or some form of computerised system designed to read the information.

Handheld barcode scanners are probably the most popular because of the flexibility of movement and the mobility they provide. A handheld barcode scanner can be used by an operator to locate the barcode and run the scanner over the barcode.

Desktop barcode scanners are also very popular and can be found in may retail outlets such as department stores and supermarkets where the item containing the barcode is located over the scanner in order to obtain the image. They can often be co-located with handheld scanners so operators can locate barcodes placed on awkward areas of a product.
