Barcode scanners are light emitting devices that are accustomed to read barcodes. Generally mounted on a computer or notebook via PS2 or RS-232, the info collected is kept on a pc for processing or storage. It is now used in many different industries such as retail or creation.
They have already been out there for many years now with brand-new variations of barcode scanners available each year. The prices can vary from only $50.00 to as high as thousands of dollars. Just how do you pick a good barcode scanner?
To reply that question, it is important you know there are 2 major classes of www.gtcodestar.com , image-based and laser-based. Image-structured barcode scanners use a camera usually embedded in a barcode scanner. The surveillance camera will capture the images and then processed by complicated image techniques to decode the barcodes. Laser-structured barcode scanners uses mirrors and lenses to read the barcodes.
Laser beam barcode scanners are often more costly than image-centered scanners. They have their own benefits and drawbacks. An image-structured barcode scanner don’t have inner movable parts therefore are more resistant to drops or knocks than laser barcode scanners. Also, image-structured barcode scanners possess a shorter scanning distance (4 to 10 inches) compared to laser barcode scanners. However, laser beam scanners are more prone to deterioration because of their lenses. They not merely have a longer scanning distance (up to 24 inches) but also are able to scan from a wider angle from the barcode.
Remember that the scanning length for both image-based and laser beam barcode scanners have previously improved dramatically over the years and I wouldn’t be surprised if a barcode producer promises an image-based scanner includes a scanning distance of 24 inches.
Here are a few questions you need to consider before getting a barcode scanner. How big is 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 recommendation is if you want a barcode scanner for lengthy range scanning, get a laser barcode scanner. For brief range scanning, use an image-based barcode scanner such as 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 tough environments where it really is expected to take a drop or knock or two, then it is advisable to obtain an image-structured barcode scanner. If it were for example being found in a retail shop, then a laser beam barcode scanner will be the best choice.
There are such a wide variety of barcode scanners available that I simply can’t explain completely in this post. If you are in doubt, seek advice from the barcode producers such as symbol or metrologic who’ve sales consultants who can do an analysis of the kind of barcode scanners needed by your business.
