“QR code” (quick response code) is the trademark for a type of matrix barcode (or two dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of that industry due to its fast readability and large storage capacity, as compared with standard UPC barcodes. The QR code consists of black modules arranged in a square pattern on a white background. The information encoded can be comprised of four standardized kinds (“modes”) of data (numeric, alphanumeric, byte / binary, and Kanji) or through supported extensions—virtually any kind of data.
