QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached.
The amount of data that can be stored in the QR code symbol depends on the datatype (mode, or input character set), version (1, â¦, 40, indicating the overall dimensions of the symbol), and error correction level.ome 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. The use of QR codes for virtual store formats started in South Korea, and Argentina, but is currently expanding globally.
