A barcode scanner also known as a barcode reader is an electronic device that decodes and physically captures information contained in barcodes. It consists of the following components, which work together to collect the data contained in a printed barcode.

  • Light source – Illuminates the barcode for proper reading.
  • Lens – Scans the barcode image.
  • Photoconductor – Translates optical impulses into electrical ones.
  • Decoder – Analyzes the data and sends the content to the scanner’s output port.  decoder can be internal or external.

After capturing an image, barcode scanners link to a host computer to pass along the scanned information. This automates the data collection process so organizations can reduce human error and expedite tasks such as tracking inventory, managing assets and monitoring point of sale transactions. The barcode represents information that identifies the manufacturer as well as the item. 

      However, there are various types of barcode scanner or readers that offer particular features and are suitable for different purposes. They come with specific functionality options to provide support for barcode reading or scanning at various sectors like retail                        stores, big industries,pharmacy and commercial places etc.

Barcodes  scanners provide better data since one barcode can be used for inventory and pricing information, it is possible to quickly obtain data on both. Furthermore, barcodes can be customized to contain other relevant information as needed. They provide fast, reliable data for a wide variety of applications.

Using a barcode system reduces employee training time. It takes only minutes to master the hand-held scanner for reading barcodes. Furthermore, employees do not have to gain familiarity with an entire inventory or pricing procedure. This also makes employee training less expensive, since they do not have to be paid for extra training time, and another employee does not have to be compensated for training them. A barcode scanner eliminates excess employees, makes companies more efficient and increases the bottom line.

Finally, a barcode scanner makes doing business much more efficient for companies and barcodes provide a method to track and store information about goods, from individual items to large stocks of thousands or even millions of items. They serve an important role and provide advantages compared with manually entering information.
