Types Of Barcode Scanners

One of the popular electronic tools are the barcode scanners that find full application such as delivering to the computer a plethora of printed barcodes. The barcode scanning system includes lenses, lens sensors, and the light source that is necessary for converting the optical to electrical impulses. The barcode reader consists of a ‘decoder circuitry’ that assesses image data of barcode. 

Classification of the Barcode Scanners

There is a host of barcode scanners such as single line as well as two-dimensional scanners. It is possible to classify these scanners based on their housing design and the technology they use. 

Classification by Technology

• Omni-directional: The omni-directional barcode scanners make use of many curved or straight scanning lines in different ‘stardust form.’ The scanners produce various kinds of beam patterns in the different orientations which permit barcode reading on multiple angles to the readers. Many readers use single rotating polygonal mirrors and different fixed mirrors to generate complicated scan patterns. 

• Camera-Based Readers: Camera-based scanners are also known as 2D barcode scanners. These readers use the procedures of image processing as well as a camera for barcode re coding. This category includes the readers of the video cameras as well as the vast ‘field-of-view.’ 

Classification By the Housing Design

• Handheld Reader: The handheld barcode readers have handle along with trigger button enabling the turning on of light source.

• Stationary Reader: The stationery barcode scanners are either table-mounted or wall-mounted and find the full application at the check-out posts at retail shops and supermarkets. 

• PDA Reader: The PDA readers are in-built barcode readers or attached barcode scanners. 

• Automatic Reader: Automatic barcode scanners are back-office tools that find full application as a barcode document reader. These tools read the documents @ 50,000/hour.

• Wireless Reader: The cordless barcode readers use batteries for operation. They serve the purpose of data transfer to the other connected devices such as a personal computer.
