Selecting A Barcode Checker?

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

They have been out there for several years now with brand-new variations of barcode scanners available every year. The prices may differ from only $50.00 to simply because high as several thousand dollars. So how do you select a good barcode scanner?

To answer that question, it is important you know there are 2 main classes of barcode scanner manufacturer , image-centered and laser-based. Image-based barcode scanners make use of a camera usually embedded in a barcode scanner. The surveillance camera will capture the images and processed by complicated image techniques to decode the barcodes. Laser-centered 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 consequently are even more resistant to drops or knocks than laser barcode scanners. Also, image-centered barcode scanners have got a shorter scanning range (4 to 10 inches) in comparison to laser beam barcode scanners. However, laser scanners are more prone to deterioration because of their lenses. They not merely have a longer scanning distance (up to 24 inches) but are also in a position 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 through the years and I wouldn’t be surprised if a barcode manufacturer promises an image-structured scanner has a scanning distance of 24 in ..

Here are a few questions you should ask yourself before obtaining a barcode scanner. The size of scanner required? Type of environment the barcode scanner will become using (outdoors, shop, warehouse)? The scanning distance required? Are they to be used hands free or hand-held? Your budget?

So my suggestion is if you need a barcode scanner for lengthy range scanning, get a laser beam barcode scanner. For brief range scanning, use an image-structured barcode scanner like a CCD barcode scanner. The environment as I asked previously also plays an important 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, then it is advisable to get an image-centered barcode scanner. If it were for example being used in a retail shop, then a laser beam barcode scanner would be the best option.

There are such a wide variety of barcode scanners available that I just can’t describe completely in this post. If you are in doubt, seek advice from the barcode producers such as symbol or metrologic who have sales consultants who can do an analysis of the kind of barcode scanners needed by your business.
