What is bar code and QR code?
Bar codes and QR codes are two types of codes used for identifying products, services, or information. A bar code is a series of vertical black bars and spaces that represent numbers and letters. It is scanned by a barcode reader to retrieve information about the item. On the other hand, a QR code is a two-dimensional code that consists of a square grid of black and white cells. It contains more information than a bar code and can be scanned using a smartphone. QR codes are widely used for marketing purposes, as they can direct users to a website or display information about a product. Both bar codes and QR codes have become essential tools in business and everyday life, simplifying processes and making information more accessible.
