Barcode scanners are light emitting gadgets 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. 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 versions of barcode scanners obtainable each year. The prices may differ from as low as $50.00 to as high as thousands of dollars. Just how do you select an excellent barcode scanner?
To reply that question, it is necessary you know there are 2 major classes of barcode scanner manufacturer , image-centered and laser-centered. Image-structured barcode scanners make use of a camera generally embedded in a barcode scanner. The camcorder will catch the images and then processed by complex image ways to decode the barcodes. Laser-centered barcode scanners uses mirrors and lenses to read the barcodes.
Laser barcode scanners are often more expensive than image-centered scanners. They possess their own advantages and disadvantages. An image-centered barcode scanner do not have inner movable parts as a result are even more resistant to drops or knocks than laser barcode scanners. Also, image-based barcode scanners have a shorter scanning length (4 to 10 inches) in comparison to laser beam barcode scanners. However, laser scanners are even more prone to wear and tear due to their lenses. They not merely have an extended scanning range (up to 24 inches) but also are able to scan from a wider angle from the barcode.
Be aware that the scanning distance 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 includes a scanning range of 24 ins.
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, store, warehouse)? The scanning length needed? Are they to be utilized hands free or hand-kept? Your budget?
So my suggestion is if you need a barcode scanner for lengthy range scanning, get a laser beam barcode scanner. For short range scanning, make use of an image-centered barcode scanner like a CCD barcode scanner. The surroundings as I asked previously also plays an essential component. If the barcode scanner is being used outside or in rugged environments where it is expected to have a drop or knock or two, then it is best 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 choice.
There are such a multitude of barcode scanners available that I simply can’t explain completely in this post. If you are in doubt, consult the barcode manufacturers such as symbol or metrologic who’ve sales consultants who are able to do an evaluation of the type of barcode scanners needed by your business.
