7 things about QR Code Master - The best use of scanning software

1. Two-dimensional bar code, also known as two-dimensional bar code, two-dimensional bar code was first invented in Japan, it is a certain geometric graphics according to certain laws in the plane (two-dimensional direction) distribution of black and white graphics record data symbol information, In the code preparation, the concept of "0" and "1" bitstreams constituting the logical basis of the computer is used to express the character numerical information using a plurality of geometries corresponding to binary, and the image input device or the photoelectric scanning device Automatic reading to achieve automatic information processing.

2. Two-dimensional code bar code is a free mobile bar code scanning software, users can use it to identify two-dimensional code / bar code.

3. It has some common bar code technology: each code has its specific character set; each character occupies a certain width; has a certain check function and so on.

4. But also has a different line of information automatically identify the function, and deal with changes in graphics and other characteristics.

5. That is, that is, sweep, smooth, direct, simple and quick, support GPRS network "0" flow control.

6. Software, decoding, continuous optimization algorithms, and optimization of query time.

7. Two-dimensional code is a readable bar code, mainly used in network resource storage, information transmission, confidential applications, logistics tracking, backup applications, etc.
