Selecting A Barcode Scanner?

Barcode scanners are light emitting products that are used to read barcodes. Generally mounted on a pc or laptop via PS2 or RS-232, the data collected is kept on a computer for processing or storage. It really is now used in many different sectors such as for example retail or creation.

They have been available for several years now with brand-new variations of barcode scanners obtainable each year. The prices may differ from as low as $50.00 to mainly because high as several thousand dollars. So how do you pick an excellent barcode scanner?

To answer that question, it is necessary you know there are 2 major classes of GTcodestar scanner , image-centered and laser-structured. Image-centered 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 usually more expensive than image-based scanners. They possess their own benefits and drawbacks. An image-based barcode scanner don’t have internal movable parts therefore are more resistant to drops or knocks than laser beam barcode scanners. Also, image-structured barcode scanners have a shorter scanning range (4 to 10 inches) in comparison to laser beam barcode scanners. On the other hand, laser scanners are even more prone to wear and tear because of their lenses. They not only have a longer scanning length (up to 24 inches) but also are in a position to scan from a wider angle from the barcode.

Be aware that the scanning range for both image-based and laser barcode scanners have previously improved dramatically over the years and I wouldn’t be amazed if a barcode producer claims an image-structured scanner has a scanning distance of 24 inches.

Here are some questions you need to consider 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-held? Your budget?

So my recommendation is if you need a barcode scanner for long range scanning, get a laser beam barcode scanner. For brief range scanning, make use of an image-based barcode scanner like a CCD barcode scanner. The environment as I asked previously also plays a significant part. 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 obtain an image-based barcode scanner. If it were for instance being used in a retail shop, then a laser beam barcode scanner will be the best choice.

There are such a multitude of barcode scanners available that I just can’t clarify completely in this post. In case you are in doubt, seek advice from the barcode manufacturers such as symbol or metrologic who have sales consultants who can do an evaluation of the type of barcode scanners needed by your business.
