Practically every item you buy in the groceries and department stores are using barcodes. Since barcodes were invented, speed and accuracy of data entry have improved a lot. Most companies are using POS systems which make every transaction faster. This helps them keep track of their items and reduce instances of shoplifting. Inventories are much easier too. So, if you’re thinking of starting a business or already have one but have not implemented barcoding, try it and see the difference.
