Scanning Methods:(follow a link to see a short sampling of our barcode scanner products from each line) Wand: Perhaps the least expensive way to scan a barcode, the wand is a pen-like device that must be in contact with the barcode. It also must be held at a certain angle, and be passed over the barcode at a consistent speed (neither too fast nor too slow). Wands present a variety of challenges that make them most useful when price is the most important factor. CCD: A CCD is a scanning "gun" that floods the barcode with light, then reads what's reflected back to it. It's more expensive than the wand, but is also more efficient and easy to use. It can only read barcodes from a close distance (less than 6" in most cases) and can only read barcodes that are no wider than the scanner itself. However, CCD's have the reputation of being highly reliable. They're great for light-to-medium retail and out-of-doors applications where sunlight makes it difficult for the scanner to"see" what is being scanned. Laser: Though laser scanners are more expensive than wands and CCDs, they are the most versatile (see "Laser Scan Engines" below) and aggressive tools for scanning barcodes. A laser beam is emitted from the scanner that either reads left-to-right and right-to-left, or vice versa. Imager: It is not possible for a wand, CCD, or laser scanner to read a matrix code (see "2D Symbologies" below). Enter the imager. These devices can not only read matrix codes, but also1D and other 2D Symbologies. And imagers can be used in the creation of ID cards that require a picture of the person. American Barcode carries the widest selection of barcode scanners in the industry. Bar coding scaner for any and all applications begin and end with American Barcode. From linear scanners to ccd scanners to fixed mount scanners for your POS needs you can get it all right here for unbelievably low pricing. |
