zxing qr code

Two-dimensional code:It is a black-and-white graph which is distributed in the plane (two-dimensional direction) by a certain geometry to record the data symbol information;The concept of 0-and 1-bit streams, which compose the logic basis of the computer, is used to represent the literal numerical information by using several geometric shapes corresponding to the binary system, and the automatic reading is realized by the image input device or photoelectric scanning device to realize automatic i
