Devices used to read barcodes are termed as barcode readers or barcode scanners. Barcode scanners are of various types based on their handling mode and technology used. Symbol scanners, HP scanners and many other types of scanners are available using various technologies. However, a right choice of scanner should be made for specific purposes. Some of the factors have to be considered while choosing a barcode scanner.

Scanner should be selected based on the environment and place where the scanner is to be used. CCD and image-based scanners can be used for outdoor environments and industrial settings.

Price of scanner is one of the important concerns. Scanners are available from very less range to expensive types. A scanner should be selected based on money that one can afford.

Barcode scanners use different technologies. Based on the model of the barcode symbology, various barcode scanners using different technologies can be used. For example, a 2D barcode scanner is required to read a 2D barcode. 2D Symbol scanners are available that can read 2D barcodes.

  • Portability is another factor that can be considered while selecting a scanner. Certain scanners can be moved around the industrial space and some are stationary.
  • Based on the size of the item on which barcode is present, selection of scanner is done. Barcodes on smaller items can be read by means of pen-wand scanner. However, other bigger items can be read by other types of scanners.
  • Checking the computer ports is another factor to be considered for selecting a scanner. USB, serial, or PS2 ports are available on a computer to which barcode scanners are connected.

All these factors have to be checked before selecting a scanner. Organizations ranging from small offices to high retail and shipping industries use barcode scanners which vary in size, model and technology.
