Barcode scanners are light emitting devices that are used to read barcodes. Generally mounted on a pc or laptop computer via PS2 or RS-232, the data collected is stored on a pc for processing or storage space. It is now used in many different industries such as for example retail or production.
They have been available for several years now with brand-new variations of barcode scanners obtainable every year. The prices may differ from as low as $50.00 to simply because high as several thousand dollars. Just how do you select a good barcode scanner?
To answer that question, it is important you know there are 2 main classes of GTcodestar scanner , image-based and laser-centered. Image-structured barcode scanners use a camera usually embedded in a barcode scanner. The camcorder will capture the images and processed by complicated image techniques to decode the barcodes. Laser-centered barcode scanners uses mirrors and lenses to learn the barcodes.
Laser beam barcode scanners are often more costly than image-centered scanners. They possess their own benefits and drawbacks. An image-structured barcode scanner don’t have internal movable parts consequently are more resistant to drops or knocks than laser beam barcode scanners. Also, image-centered barcode scanners have got a shorter scanning distance (4 to 10 inches) in comparison to laser beam barcode scanners. However, laser beam scanners are even more prone to deterioration due to their lenses. They not merely have a longer scanning range (up to 24 inches) but also are able to scan from a wider position from the barcode.
Remember that the scanning length for both image-based and laser beam barcode scanners have already improved dramatically through the years and I wouldn’t be amazed if a barcode manufacturer promises an image-centered scanner includes a scanning length of 24 in ..
Here are a few questions you should consider before getting a barcode scanner. The size of scanner required? Kind of environment the barcode scanner will end up being using (outdoors, store, warehouse)? The scanning distance needed? 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-structured barcode scanner like a CCD barcode scanner. The environment as I asked earlier also plays an important part. If the barcode scanner has been used outdoors or in rugged environments where it is expected to have a drop or knock or two, then it is advisable to get an image-based barcode scanner. If it were for instance being found in a retail shop, then a laser barcode scanner will be the best option.
There are such a multitude of barcode scanners obtainable that I simply can’t explain completely in this post. If you are in doubt, consult the barcode manufacturers such as for example symbol or metrologic who’ve sales consultants who can do an evaluation of the type of barcode scanners required by your business.
