So, how do they work? Well, most bar code scanner uses imaged based scanners or laser based scanners to read the lines of the bar code. The image-based barcode scanners use a camera that captures the image of the barcode and then processes it using complex image techniques. The Laser-based barcode scanners use mirrors and lenses to read the barcodes.

Each barcode has specific symbols defined as a series of bars in a barcode. The way to differentiate the barcode is by the height and width as well as the bar spacing. Each strip of bar can represent a number, character or alphanumeric character depending on the bar code system used.

Bar code scanners are available from $ 50 upwards depending on the scanning mechanism that is being used. Usually, laser barcode scanners are more expensive than image-based scanners because of the mirrors and lenses that are employed in reading the bar codes.

Determining the kind of bar code scanner that you want to buy for your new office depends on your budget and the use to which you are going to put the bar code scanners to. You need to determine whether the bar code scanner needs to be mobile and also whether the bar code scanner will be put to a lot of use. Image-based barcode scanners do not have internal movable parts and therefore are more resistant to knocks. The image based bar code scanner is also very useful for scanning from a shorter distance.

Laser bar code scanners need to be cared for more carefully than image based bar code scanners because their lenses are more prone to wear and tear. However, the advantage of the laser bar code scanner is that they are very convenient to use for scanning from short and long distance. So, they are the ideal bar code scanners to use in grocery stores.

The most popular type of bar code scanners are the wireless bar code scanners. These bar code scanners connect to the base station or workstations wirelessly and can transmit data back to the terminal within a specified range.

When buying a bar code scanner for your office you need to carefully consider the pro and cons of both the image based bar code scanner and the laser based bar code scanner. Once this is done you can you can shop around for good prices on bar code scanners.
