What does QR code mean?

A QR code is a two-dimensional barcode that stores information in the form of black and white squares. After scanning it with a phone camera or another device, it can take the user to a web page, product, payment form, contact details or other digital content. Compared to a classic barcode, it holds more data and can be read from different directions. In e-commerce and marketing, it is used on packaging, flyers, receipts, promotional materials or in brick-and-mortar stores. A QR code makes it easier to connect the offline and online worlds and lets users quickly open the desired content without typing an address.
