Barcode scanners are light emitting products that are accustomed to read barcodes. Usually mounted on a computer or notebook via PS2 or RS-232, the info collected is stored on a computer for processing or storage. It really is now used in many different industries such as for example retail or creation.
They have already been out there for several years now with new versions of barcode scanners obtainable every year. The prices can vary from as low as $50.00 to simply because high as thousands of dollars. So how do you pick an excellent barcode scanner?
To remedy that question, it is important you know there are 2 major classes of GTcodestar scanner , image-based and laser-centered. Image-structured barcode scanners use a camera generally embedded in a barcode scanner. The camcorder will catch the images and then processed by complex image techniques to decode the barcodes. Laser-structured barcode scanners uses mirrors and lenses to learn the barcodes.
Laser barcode scanners are usually more expensive than image-centered scanners. They have their own advantages and disadvantages. An image-structured barcode scanner do not have inner movable parts therefore are more resistant to drops or knocks than laser beam barcode scanners. Also, image-based barcode scanners have got a shorter scanning distance (4 to 10 inches) compared to laser beam barcode scanners. On the other hand, laser beam scanners are more prone to deterioration due to their lenses. They not merely have a longer scanning length (up to 24 inches) but are also able to scan from a wider angle from the barcode.
Remember that the scanning range for both image-based and laser beam barcode scanners have previously improved dramatically through the years and I wouldn’t be surprised if a barcode manufacturer claims an image-based scanner has a scanning range of 24 in ..
Here are a few questions you should ask yourself before getting a barcode scanner. How big is scanner required? Kind of environment the barcode scanner will become using (outdoors, shop, warehouse)? The scanning length needed? Are they to be used hands-free or hand-kept? Your budget?
So my suggestion is if you need a barcode scanner for lengthy range scanning, get yourself 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 essential part. If the barcode scanner is being used outdoors or in rugged environments where it is expected to have a drop or knock or two, after that it is best to get an image-centered barcode scanner. If it were for instance being found in a retail store, then a laser barcode scanner will be the best choice.
There are such a wide variety of barcode scanners available that I just can’t clarify 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 are able to do an analysis of the type of barcode scanners required by your business.
