What is a 2d barcode scanner
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, the laser scanners have substituted the 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.
