QR-code (English quick response -. Quick response) - a matrix code (two-dimensional barcode), developed and presented by the Japanese company Denso-Wave.
The huge popularity of barcodes in Japan has led to the fact that the amount of information encoded in them, soon ceased to hold the industry. The Japanese began to experiment with new ways of modern coding small amounts of information in a graphic image.

Unlike the old barcode, which is scanned with a thin beam, QR-code is determined by a sensor or camera smartphone as a two-dimensional image. Three square images in the corners and smaller squares around the clock enable normalization code size and orientation, and the angle at which the sensor is to the image surface. Points are converted to binary numbers with check checksum.

The main advantage of the QR-code - it's easy detection scanning equipment that makes it possible to use in trade, production and logistics.
