A QR code (short for quick response code) is a type of matrix barcode (or two-dimensional barcode) invented in 1994 by the Japanese automaker Denso Wave. A barcode is a machine-readable optical label that can contain information about the item it is attached to. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or app. A QR code uses four standardized coding modes (numeric, alphanumeric, byte / binary and kanji) to store data efficiently; extensions can also be used.
The Quick Response system has become popular outside the automotive industry due to its fast readability and greater storage capacity than standard UPC barcodes. Applications include product tracking, item identification, time tracking, document management, and general marketing.
A QR code consists of black squares arranged in a square grid on a white background, which can be read by an imaging device such as a camera and processed using Reed-Solomon error correction until the image can be interpreted in appropriately. The required data is then extracted from the patterns present in the horizontal and vertical components of the image.
