What is a bar code module

What do I believe that many people do not understand the word bar code module, in fact, bar code module is what we say scanning module, the first bar code module is infrared scanning, so at that time can only scan bar codes, but with the development of science and technology, the current bar code module can scan bar codes and two-dimensional codes, so the current bar code module is a scanning module. Today we are focusing on the introduction of today's product bar code module.

There are many types of bar code modules, but the most common are 1D and 2D, 1D bar code is linear bar code or traditional bar code, this kind of bar code module can only be used to store simple information, and 2D bar code is relatively comprehensive, it can become a matrix bar code or two-dimensional code, can store more information. It even includes text, urls, images, and videos.

Bar code module is mainly used as the function of data acquisition, processing and transmission, in the data collection, it can quickly read the information in the bar code through the special scanning equipment, and then in the docking database system, the collected data for instant analysis and processing, and finally in the data transmission, through a variety of communication protocols, Ensure that information is passed on accurately to the next node or end user.

Today's bar code module application is very wide, covering a variety of industries, it can complete the automatic control and quality tracking of the production line in the manufacturing industry, but also help enterprises to achieve fine management, improve production efficiency. Then in the logistics industry, the location of the package can be tracked in real time by attaching barcode labels to the goods, improving the sorting efficiency and accuracy. In the retail industry, by scanning the bar code of goods, cashiers can quickly complete the checkout, and customers can also scan the code through the mobile phone to compare prices, enjoy a more convenient shopping experience.

But no matter what the field, bar code module has shown its value and role, it not only changed our way of life, but also promoted the progress of society, and we also have reason to believe that in the future with continuous technological innovation, the role of bar code module will gradually expand, when its scope of application will be further expanded. Of course, it can also bring more convenience to our life.
