A barcode is a machine-readable optical label that contains information about the object to which it is attached. A QR is a two-dimensional type of barcode that is easily read by a digital device and stores information as a series of pixels in a square grid that looks like a black and white pattern. . A QR code, unlike a barcode, can be read in two directions - horizontally and vertically. This allows you to store more data in it. When scanning a QR code, the user has instant access to this data. The QR code system has become popular due to its fast reading capability and higher capacity than UPC standard barcodes. These days, QR codes are used in a variety of industries for storing data (links to websites, phone numbers or texts), as well as for providing Wi-Fi access, sending and receiving payment information, and other purposes. How do QR codes work? A QR code pattern stores an encrypted sequence of data in binary format (1 and 0) as a matrix. Each individual grid cell is assigned a value depending on the color (black or white). The cells are then grouped into larger patterns. The keys of the encoded data contain duplicates, so if the surface of the QR code is damaged to a certain extent, it can be read.
