A Snapshot on Barcode Scanners

The barcode scanners are the electronic tools that are used for reading and deliver a multitude of the printed barcodes to a computer. These scanners include lens sensors, lenses as well as the ‘light source’ for the purpose of translating all the ‘optical impulses’ to the ‘electrical impulses’. The barcode scanner comprises of the decoder circuitry which analyses the image data of the barcode which the sensor provides and sends the barcode content to the scanner’s ‘output port’.

Classification of the Barcode Scanners
There are many kinds of the barcode scanners from the single line barcode scanners to the ‘two-dimensional’ imaging scanners which can be classified based on the technology employed and the housing design.

Based on the Technology Used
  Omnidirectional Barcode Readers:The omnidirectional scanners use a series of the straight or curved scanning lines in various in the ‘starburst form’. The scanners generate different patterns of beams in various orientations that permit rea…

A Rundown of the Types of Barcode Scanners

The electronic device, the barcode scanners can read and output ‘printed barcodes’ to a computer. It has a light sensor, light source, and a lens. The ‘light sensor’ translates ‘optical impulses’ to ‘electrical impulses’. They contain ‘decoder circuitry’ which analyses the ‘barcode’s’ image data offered by the sensor as well as sending the ‘barcode’s content’ to the scanner’s ‘output port’.

The Barcode Scanner Can be Classified Based on Technology
Pen-Type Barcode Scanners:The ‘pen-type’ scanners consist of the light source and the photodiode which is placed on the pen’s or wand’s tip. The photodiode of the scanner measures the intensity of light which is reflected from the source of light when the tip of the barcode crosses space in each of the bars as well as the printed code.
Laser Barcode Scanners:The laser-type barcode scanners work on the same principle as that of the pen scanners with the difference that it uses the ‘laser beam’ as the ‘light source’. This type of scanners uses t…
