2D Bar Code Scanner 

The development of two-dimensional (2D) barcodes not only brought convenience to our daily life but also became commercially successful when they were used to automate supermarket checkout systems, a task for which they have become almost universal.  They allowed you to effectively control your stock with less time and effort. With a 2D barcode scanner to read a series data, the data can be displayed on a computer. The difference between the 2D and 1D barcode is the size of data; 1D barcode can only display numbers, while 2D barcode can present more information in a small space.
