Barcode readers are used to capture the information from barcodes. They contain a reader and a decoder, which are connected to a computer by using compatible ports. Earlier barcode readers used to had a fixed light and a single photo sensor. The modern barcode scanners have polygonal mirrors and laser scanning technology to get great efficiency in work.
There are different types of barcode scanners with different features, such as:
- LED scanner: LED readers are also referred to as CCD scanners, CCD is photo imaging sensor and does not require a light source.
- Laser reader: Laser scanners are more expensive than LED scanners and they are capable to scan from longer distances. Symbol barcode scanner can read barcodes from longer distance by using laser technology.
- Imager scanner: An image of the linear barcode is taken by these scanners. They do not have moving parts, so they are more rugged.
- 2D imaging scanner: 2D image of linear barcode is taken by these scanners by using a camera. They use 2D barcode types like datamatrix and common linear barcode types as well, to scan barcodes.
- Hand held scanner: This scanner has a handle and a trigger button for switching on the light.
Barcode readers are designed to increase the speed of the data retrieval and data processing. Because of these reasons, they are used for commercial establishments, libraries, counters, any point of sale and more.
In order to have a better inventory management and customer service, choosing a best barcode scanner like Symbol scanners is important.
