Usually attached to a compute r or laptop via PS2 or RS-232, the data collected is stored on a compu ter for processing or storage. It i s now used in many different indust ries such as retail or production. They have been on the market for ma ny years now with new versions of b arcode scanners available every yea r. The prices can vary from as low as $50.00 to as high as several tho usand dollars. So how do you pick a good barcode scanner? To answer that question, it is impo rtant you know there are 2 major cl asses of barcode scanners, image-ba sed and laser-based. Image-based ba rcode scanners use a camera usually embedded in a barcode scanner. The camera will capture the images and then processed by complex image te chniques to decode the barcodes. La ser-based barcode scanners uses mir rors and lenses to read the barcodes. Laser barcode scanners are usually more expensive than image-based sca nners. They have their own pros and cons. An image-based barcode scann er do not have internal movable par ts therefore are more resistant to drops or knocks than laser barcode scanners. Also, image-based barcode scanners have a shorter scanning d istance (4 to 10 inches) compared t o laser barcode scanners. On the ot her hand, laser scanners are more p rone to wear and tear due to their lenses. They not only have a longer scanning distance (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 bar code scanners have already improved dramatically over the years and I wouldn_t be surprised if a barcode manufacturer claims an image-based scanner has a scanning distance of 24 inches. Here are some questions you need to ask yourself before getting a barc ode scanner. The size of scanner re quired? Type of environment the bar code scanner will be using (outdoor s, shop, warehouse)? The scanning d istance required? Are they to be us ed hands free or hand-held? Your bu dget? So my suggestion is if you need a b arcode scanner for long range scann ing, get a laser barcode scanner. F or short range scanning, use an ima ge-based barcode scanner such as a CCD barcode scanner. The environmen t as I asked earlier also plays an important part. If the barcode scan ner is being used outdoors or in ru gged environments where it is expec ted to take a drop or knock or two, then it is best to get an image-ba sed barcode scanner. If it were for example being used in a retail sho p, then a laser barcode scanner wou ld be the best choice. There are such a wide variety of ba rcode scanners available that I jus t can_t explain completely in this article. If you are in doubt, consu lt the barcode manufacturers such a s symbol or metrologic who have sal es consultants who are able to do a n analysis of the type of barcode s canners needed by your business.
