WHAT ARE BARCODES?
Simply put, They are machine-readable codes or numbers represented by a pattern of parallel lines of varying widths, printed on and identifying Items/products.

WHAT ARE BARCODES USED FOR?
Barcodes are used by businesses and organizations to identify and track products, assets and other items. They turn manual product look-ups into an automated process that’s efficient and virtually error free. In practice, barcodes are unique for each item and linked to centralized management in a computer POS software system allowing incredible increases in productivity and efficiency.

If you sell large number of products and track them manually, barcodes can work wonders for you. They automate product management so that when you sell a product, for example, a scanner reads the attached bar code, identifies the unique number associated with it, and completes the sale, pulling up the price and reducing your inventory by one. All of this happens in a fraction of a second—without errors since there’s no manual data entry.

TYPES OF BARCODES
There are Different types of barcodes, used for different applications. prominent are 1D (Linear), 2D/QR codes.

  • 1D (linear) barcodes

They’re used to represent product codes such as European EANs, UPCs, ISBNs, Above is a 1D barcode image, The number is printed on the bar code purely for reference—in case the bar code is damaged and you need to enter it manually. It’s not read by the bar code scanner.
  • 2D barcodes
    These are most commonly seen on carrier shipping labels and have a more complex and robust coding methodology. You probably won’t put these on products, so we won’t go into detail about them here.
  • QR codes
    Quick response (QR) codes can be used to encode several types of data—text, phone numbers, business cards, and more. Most commonly, they’re used for web addresses (URLs), so that when they’re scanned with a phone or tablet, the user is taken directly to that URL.
