Selecting A Barcode Scanning device?

Barcode scanners are light emitting products that are used to read barcodes. Usually attached to a pc or notebook via PS2 or RS-232, the data collected is kept on a pc for processing or storage space. It is now used in many different sectors such as for example retail or production.

They have been out there for several years now with fresh variations of barcode scanners obtainable each year. The prices may differ from only $50.00 to as high as several thousand dollars. Just how do you select a good barcode scanner?

To answer that question, it is important you understand there are 2 main classes of barcode scanner manufacturer , image-based and laser-centered. Image-structured barcode scanners use a camera generally embedded in a barcode scanner. The video camera will catch the images and processed by complex image techniques to decode the barcodes. Laser-structured barcode scanners uses mirrors and lenses to read the barcodes.

Laser beam barcode scanners are usually more costly than image-structured scanners. They have got their own advantages and disadvantages. An image-structured barcode scanner don’t have internal movable parts therefore are more resistant to drops or knocks than laser beam barcode scanners. Also, image-structured barcode scanners have got a shorter scanning distance (4 to 10 inches) compared to laser beam barcode scanners. On the other hand, laser scanners are even more prone to deterioration due to their lenses. They not only have a longer scanning distance (up to 24 inches) but are also able to scan from a wider position from the barcode.

Remember that the scanning distance for both image-based and laser barcode scanners have previously improved dramatically over the years and I wouldn’t be surprised if a barcode manufacturer claims an image-based scanner includes a scanning range of 24 ins.

Here are a few questions you have to ask yourself before getting a barcode scanner. How big is scanner required? Kind of environment the barcode scanner will end up being using (outdoors, store, warehouse)? The scanning length required? Are they to be used hands-free or hand-held? Your budget?

So my suggestion is if you need a barcode scanner for long range scanning, get yourself a laser barcode scanner. For short range scanning, make use of an image-centered barcode scanner such as a CCD barcode scanner. The surroundings as I asked previously also plays a significant part. If the barcode scanner has been used outdoors or in rugged environments where it really is expected to have a drop or knock or two, after that it is advisable to get an image-based barcode scanner. If it were for example being used in a retail store, then a laser beam barcode scanner will be the best choice.

There are such a multitude of barcode scanners obtainable that I simply can’t clarify completely in this post. If you are in doubt, consult the barcode producers such as for example symbol or metrologic who have sales consultants who can do an analysis of the type of barcode scanners needed by your business.
