Barcode scanners are light emitting products that are used to read barcodes. Generally attached to a computer or laptop computer via PS2 or RS-232, the data collected is kept on a pc for processing or storage. It is now found in many different sectors such as for example retail or production.
They have already been out there for several years now with fresh versions of barcode scanners available every year. The prices may differ from as low as $50.00 to mainly because high as thousands of dollars. Just how do you pick an excellent barcode scanner?
To answer that question, it is necessary you know there are 2 major classes of www.gtcodestar.com , image-based and laser-structured. Image-centered barcode scanners make use of a camera usually embedded in a barcode scanner. The surveillance camera will capture the images and then processed by complex image ways 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-structured scanners. They have their own pros and cons. An image-structured 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 possess a shorter scanning distance (4 to 10 inches) in comparison to laser barcode scanners. On the other hand, laser scanners are 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.
Be aware that the scanning range for both image-based and laser barcode scanners have previously improved dramatically through the years and I wouldn’t be surprised if a barcode producer claims an image-structured scanner has a scanning length of 24 ins.
Here are some questions you have to consider before obtaining a barcode scanner. The size of scanner required? Type of environment the barcode scanner will end up being using (outdoors, store, warehouse)? The scanning distance needed? Are they to be utilized hands-free or hand-kept? Your budget?
So my recommendation is if you need a barcode scanner for long range scanning, get a laser barcode scanner. For short range scanning, use an image-structured barcode scanner like a CCD barcode scanner. The surroundings as I asked previously also plays an important component. If the barcode scanner is being used outside or in rugged environments where it is expected to take a drop or knock or two, then it is best to obtain an image-based barcode scanner. If it were for instance being used in a retail store, then a laser beam barcode scanner will be the best choice.
There are such a wide variety of barcode scanners obtainable that I simply can’t explain completely in this post. If you are in doubt, consult the barcode producers 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.
