QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode).
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, processed and interpreted. The required data is then extracted from patterns that are present in both horizontal and vertical components of the image.
QR codes have become common in consumer advertising. Typically, a smartphone is used as a QR code scanner, displaying the code and converting it to some useful form (such as a standard URL for a website, thereby obviating the need for a user to type it into a web browser).
QR code has become a focus of advertising strategy, since it provides a way to access a brand's website more quickly than by manually entering a URL.
QR codes storing addresses and URLs may appear in magazines, on signs, on buses, on business cards, or on almost any object about which users might want information.
Users with a camera phone equipped with the correct reader application can scan the image of the QR code to display text, contact information, connect to a wireless network, or open a web page in the telephone's browser.
