In buying a barcode scanner, it is important to check first a few factors before buying the item right away. Here is a quick rundown of the characteristics you should check before purchasing a scanner:
• Scan Range – This is simply a choice between linear imagers or laser ones. Basically, it will be better to choose linear if the image’s distance is below 18 inches. If it goes the other way around, pick laser.
• Barcode Types – Most scanners have a general ability to scan certain types of barcodes. This is usually comprised of Codes 39 and 128 along with EAN/UPC. The latest linear image scanners have the best output in codes with higher densities in X-dimensions from 2 to 5 mil and between 10 to 20 mil up to 8 inches of barcode width.
• Environment – You should pick a scanner with a standard ABS plastic casing if you plan to use it only in retail application. But if you plan to use the scanner for warehouse applications, better get a harder casing which is more durable.
• Computer Screen Barcodes – Linear imagers are better options if you plan to scan more barcodes from the monitor rather than having these printed out.
• Performance – Of course the performance is the main factor for your judgment. This is the overall result of how the scanner functions. Here you judge the scanning zone, the range, and the neatness of the scanner’s job. Linear imagers are most suitable for flat surfaces, as these scan when the scanner’s nose detects the code. Some of these may scan within 2 inches, while some can go up to 18 inches.
These are the factors that one must check before making a purchase of barcode scanners. Be sure to consult this short list before making any purchases.
