There are four main types of barcode scanners, also known as barcode readers: wired, wireless, mobile and stationary. All barcode scanners feature a red or infrared light that, when emitted, hits the barcode and is reflected back to a special sensor. The decoder then decodes what, to the human eye, is just a black-and-white image. All the pertinent product information—name, contents and price—is thus uniquely identified and can be used, for example, to search a database and determine where the item is found and how much it costs.
Companies use barcode scanners extensively to access data which they intend to process in some way. For example, barcodes are used to track packages travelling around the globe. This allows delivery services to inform the customer of the package’s location and when it’s expected to arrive—added value at its finest. Barcode scanners are equally important in warehouses, where they record goods coming in and going out. But other uses are just as relevant, such as ensuring that the right medication is administered in medical environments.
‘Do I need a presentation scanner, radio scanner, fixed scanner or hand-held scanner? Should I go with laser technology or LED area imaging?’ The barcode scanner you choose depends on how your business plans to use it. Laser scanners, for instance, have an impressive range but can only read 1D barcodes. Area-imaging technology, on the other hand, is able to scan 2D barcodes, which hold more data. High-end area-imaging models can even capture digital images. Our Bechtle online shop offers numerous filter options to help you narrow down your choices. Select criteria such as the scanner’s protection rating and available connections, for example USB, serial or PS/2.
