It is important to know the 2D barcodes, prior to discussing the 2D barcode scanner. To begin with, 2D barcodes are an improved version of the 1D barcodes which contain more data as compared to the traditional barcodes. The linear barcodes usually get wider with additional data; however, the 2D barcodes have perpendicular dimensions, to store more data in them. The complicated symbologies of such barcodes require a high-end mechanism to decode the characters. Therefore, in the present market, laser scanners have substituted conventional scanners. With the increasing inventories in the industrial scenario, 2D barcode scanners are becoming exceedingly popular.
2D barcode scanners happen to be advanced scanning devices that can decode complex 2D barcodes. They employ CCD and imaging technologies to get the right output to the station. The scanner could be integrated with a computer through a USB port or a Bluetooth device, which would then be configured with some software to get the data into a specific file.
All those 2D barcode scanners that employ the CCD technology contain a series of lights as sensors located on the head of the scanner. As soon as a barcode is drawn near these scanners, they would automatically detect the light reflexes and the image would be decoded in the process. On the other hand, the imaging technology uses a little camera which is placed on the head of the scanner. The camera is equipped with light sensors all around and the 2D array is captured as soon as the barcode image is taken. The decoded data is then sent to the computer software, which connects it to the output station. In both these technologies, the time employed is less than one second. With the increasing requirements to store data efficiently, these scanners are in great demand for tracking purposes.
2D Barcodes or two-dimensional barcodes are the merely higher level of barcodes that possess the capacity to store huge volumes of data in two dimensions, without actually becoming wider in size. The linear barcodes are known to have its own limitations when it comes to data storage and they have always been perceived as license plates, used commonly as database keys.
There are special scanners that read such 2D codes and are called 2D-Scanners. The 2D scanner usage involves the improvements in these barcodes and acts more like a portable database scanner that reveals important information every time information on the bar code is scanned. 2D codes are also referred to as the matrix codes since the matrix happens to be an appropriate representative of 2D symbols.
2D barcodes would be able to save data across the length and the width of the specific barcode. They were introduced after there were space limitations, although the data requirement was mandatory. Data entry into such codes is extremely fast and there are as many as 20 different symbologies for 2D barcodes. The 2D scanner usage employs the handheld scanners with mobile beams that would sweep the label effortlessly.

2D bar codes are robust and cannot be abused or corrupted, therefore they can ultimately store more data. 2D bar code symbolics falls into different categories – matrix and stack. They could be used for packing lists, licenses, patients’ records in health care organizations and tax forms. 2D bar codes are a part of the comprehensive solution for scanners and can be connected to the station through the keyboard. The installation is fairly simple and the 2D scanner usage authorizes trouble-free data editing, formatting, remapping, etc without any special software application.
2D barcodes could be incorporated in different kinds of business or software models, without any intricacies. As compared to the traditional barcode, much more information could be stored here and they happen to be more versatile as well.
