Introduction to QR code principle:

Two dimensional code records data symbol information with black-and-white graphics distributed on the plane according to a certain law with a specific geometric figure. In coding, it skillfully uses the concept of 0 / 1 bit stream constituting the internal logic basis of the computer, and uses several geometric bodies corresponding to binary to represent text numerical information, Automatic reading through image input equipment or photoelectric scanning equipment to realize automatic information processing; QR code can express information in both horizontal and vertical directions, so it can express a large amount of information in a small area
