There are two general classes of barcodes: one-dimensional (1D or linear) and two-dimensional (2D). The difference between 1D and 2D barcodes is determined by the layout and amount of data that can be stored in each, but both can be used effectively in several automatic identification programs.

The 1D barcode is the most used and is especially used in retail stores for product labeling. In addition, it is also often used in the warehouse industry for marking locations and bins. A 1D barcode is a visual representation of information that can be read and decoded mechanically. Reading and decoding are done using a scanner, like a laser beam, that reflects the code of the reading head in the scanner, which interprets the information stored in the lines. The barcode can therefore be seen as the personal identification number of the goods. As the social security number tells a person’s birthday, the barcode gives information about the origin of the product in the form of a numerical code.
The 2D barcode can contain up to 100 times as much information as the 1D barcode and more complex information, such as links and pictures. 2D barcodes always have the same size and are typically easier to scan at long distances. They are used, among other things, for labeling medical products, downloading apps, sharing information with consumers by placing the codes on advertisements on the bus or standers in the city, and so on. 2D barcodes can only be read with an Imager barcode scanner. 2D is not yet widely used in retail, as 2D scanning is not yet available for output boxes, but the 2D barcode is predicted to have a bright future. This is due to the large amount of data the codes can contain, as well as many of the scanners currently manufactured being able to scan 2D.

Using Mobile WMSTasklet Factory always recommends imager barcode scanners for 1D and 2D scanning over the laser scanner for only 1D scanning.
Next up, we will go deeper into the different types of 1D barcodes, what information they hold, and where they are used.
