The majority of QR code users used them to make payments or to access product and menu information. In 2022, 89 million people in the United States scanned a QR code using their mobile devices, up by 26 percent compared to 2020. Some 58% of those users scanned a QR or barcode from their homes, while 39% scanned from retail stores 53% of the 14 million users were men between the ages of 18 and 34. ĭuring the month of June 2011, 14 million American mobile users scanned a QR code or a barcode. The QR code has become one of the most-used types of two-dimensional code.

There are a great many QR code generators available as software or as online tools that are either free, or require a paid subscription. QR codes may be used to display text to the user, to open a webpage on the user's device, to add a vCard contact to the user's device, to open a Uniform Resource Identifier (URI), to connect to a wireless network, or to compose an email or text message. Adoption QR codes can be displayed on buildings, such as this one being painted in Cape Town.Īs of 2023, QR codes are used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile-phone users (termed mobile tagging). The quadrangular configuration of the QR code system consolidated the data of the various bar-code labels with Kanji, Kana, and alphanumeric codes that were printed onto single label. The functional purpose of the QR code system was to facilitate keeping track of the types and numbers of automobile parts, by replacing individually-scanned bar-code labels on each box of auto parts with a single label that contained the data of each label. The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board the pattern of position detection was found and determined by applying the least-used ratio (1:1:3:1:1) in black and white areas on printed matter, which cannot be misidentified by an optical scanner. The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. Compared to standard UPC barcodes, the QR labelling system was applied beyond the automobile industry because of faster reading of the optical image and greater data-storage capacity in applications such as product tracking, item identification, time tracking, document management, and general marketing. To efficiently store data, QR codes use four standardized modes of encoding: (i) numeric, (ii) alphanumeric, (iii) byte or binary, and (iv) kanji. Whereas a barcode is a machine-readable optical image that contains information specific to the labelled item, the QR code contains the data for a locator, an identifier, and for web-tracking. The required data are then extracted from patterns that are present in both the horizontal and the vertical components of the QR image. A QR code consists of black squares arranged in a square grid on a white background, including some fiducial markers, which can be read by an imaging device, such as a camera, and processed using Reed–Solomon error correction until the image can be appropriately interpreted. A QR code for the URL of the English Wikipedia Mobile main pageĪ QR code ( quick-response code) is a type of two-dimensional matrix barcode, invented in 1994, by Japanese company Denso Wave for labelling automobile parts.
