Speaking of barcode scanner, this is actually a term that is commonly used to describe a light emitting device that are used for the purpose of reading barcodes. We are sure that you have already seen a barcode and even watched how it work since they are commonly being used at supermarkets, departments stores and malls as well and surely, you have noticed as well how they are being connected to a laptop or a computer by means of using an RS-232 and a PS2, with the data collected stored on a computer for both processing and storage. In this present day and time that we live in, there are now so many different industries that are making the most use of barcode scanners and some of these industries are the production and retail industries.
There are other things that you have to be aware of when it comes to barcode scanners like the fact that they have been around for quite some time already and there have been new versions being released or available every year. As for the prices, we bet that you are already curious about that and we want you to know that it can vary from as low as fifty dollars to as high as several thousand dollars. Now, the question lies on how you are going to choose the right barcode scanner?
To answer that questions that was asked earlier on in this article, one very important thing that you should be aware of is the fact that there are two major classes of barcode scanners and these two classes are the laser based and the image based. The first one that we will tackle is the image based and when we say image based, we are actually referring to barcode scanners that are typically using cameras that are embedded in a barcode scanner. The camera that is embedded in the barcode scanner will then capture the image and have that image processed by the use of a complex image techniques to decode the barcodes. On the other hand, when it comes to laser based barcode scanners, it usually uses mirrors as well as lenses for the barcodes to be read.
If we are going to talk about the prices of the two major classes of barcode scanners, we want you to know that the laser based barcode scanners is more expensive that the image based one.
There are several other factors that you should consider when selecting the finest barcode scanner there can be like knowing the type of environment you will be using it to, the budget you have as well as the size of the barcode scanner you need, among other significant factors.
