Sitemap Every time I go the mall and see barcode scanners along the counter area, it reminds me of my previous job. I’ve been working in a bar coding company for almost 13 years and we deal with bar code scanners, printers and other bar code supplies! Barcode scanner is very useful for retail, warehousing and even for inventory use. It makes your work faster and accurate as it will read the barcode from the product or item. So mostly barcode scanners now are very much use in many ways! So glad that in my 13 years of working in I.T company, I know exactly how it works for companies. We have several clients who are satisfied to have barcode readers.
