QR Code Recognition System

A QR Code (abbreviated from Quick Response Code) is a two dimensional barcode invented by the Japanese corporation Denso Wave. Information is encoded in both the vertical and horizontal direction, thus holding up to several hundred times more data than a traditional bar code. Data is accessed by capturing a photograph of the code using a camera (e.g. built into a smartphone) and processing the image with a QR reader. QR Codes have rapidly gained international popularity and found widespread adoption, especially in Japan where its ability to encode Kanji symbols by default makes it especially suitable. Popular uses include storing URLs, addresses and various forms of data on posters, signs, business cards, public transport vehicles. Indeed, this mechanism has a vast number of potential applications.
