Difference between 2D and 1D barcode scanner

What is the difference between 2D barcode scanner and 1D barcode scanner? To figure out the difference between the two, first of all, we need to have a simple understanding of the barcode. The one-dimensional bar code is composed of vertical black bars and white bars, and the thickness of the stripes is different. Usually, there have English letters or Arabic numerals under the stripes. The one-dimensional bar code can identify the basic information of the product, such as the product name, price. Etc., but can not provide more detailed information on the goods, If need more information, have further cooperation with the computer database. Therefore, the 1D barcode scanner can only scan one-dimensional barcodes.

With the development of the social economy and the advancement of the information age, one-dimensional bar codes can no longer meet people's needs, so two-dimensional bar codes appear. It is usually a square structure, not only consists of horizontal and vertical bar codes, but also has a polygonal pattern in the code area. Similarly, the texture of the two-dimensional code is also black and white, different in thickness and lattice form.

What is the function of 2D barcode? Compared with the one-dimensional barcode, the two-dimensional code not only has the identification function, but also displays more product details. For example, clothes can not only display the name and price of the clothes, but also what materials are used, the percentage of each material, cloth size, the size of the person, and some washing precautions, without the need from computer database,which will more easy and convenient. In order to adapt to the new requirements, two-dimensional barcode scanner was developed based on a one-dimensional scanner, so the 2D barcode scanner can scan both the one-dimensional barcode and the two-dimensional barcode.

So in summary, the main difference is that the 1D bar code scanner only scan one-dimensional bar code, But 2D bar code scanner can scan one-dimensional bar code and also two-Dimensional barcode. Both are bar code devices developed in the context of social needs.
