Qr codes are a common form of data storage and transmission, consisting of a set of black and white pixels used to represent data and information. Each QR code is unique because it consists of a randomly generated set of data characters that have unique values.

The reason for this uniqueness is that QR codes consist of a set of rectangular patterns defined by rules. These rectangular patterns usually consist of a rectangle and four equilateral triangles of equal length to the sides of the rectangle, the vertices of which connect each of the four vertices of the rectangle. The triangles are fixed in shape, size and position, so each QR code is unique and has a unique way of encoding and decoding.

In order to ensure the uniqueness of each two-dimensional code, the process of generating two-dimensional code is very complicated. Algorithms that generate QR codes typically use a method called "encoding," which generates a random number and combines that number with a set of binary number characters. These binary number characters are unique because they can only be generated by the generation algorithm.

In the process of two-dimensional code generation, the generation algorithm will generate a series of data characters, and then these data characters are arranged in a certain order. The resulting QR code is a rectangular pattern of black and white pixels with a unique encoding and decoding method.

In addition to the complexity of the coding method, the process of generating QR codes also needs to consider a number of other factors, such as the Angle of light, the cleanliness of the surface of the QR code, the accuracy of the data, and so on. Therefore, each QR code is unique, which is one of the reasons why QR codes are widely used in data storage and transmission.

In short, each QR code is unique because it consists of a randomly generated set of data characters that have unique values. This uniqueness ensures that each QR code is unique and can be correctly identified and decoded. In the field of data storage and transmission, QR code has become a very important technology, because it has the characteristics of efficiency, reliability and security, which can meet the needs of more and more applications.
