Also, image-based barcode scanners have a shorter scanning distance (4 to ten inches) compared to laser barcode scanners. On the other hand, laser scanners are a lot more prone to wear and tear due to their lenses. They not only have a longer scanning distance (up to 24 inches) but also are in a position to scan from a wider angle from the barcode.
Be conscious that the scanning distance for each image-based and laser barcode scanners have currently enhanced substantially over the years and I wouldnt 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 your self prior to finding a barcode scanner. The size of scanner essential? Kind of environment the barcode scanner will be using (outdoors, shop, warehouse)? The scanning distance needed? Are they to be utilised hands free or hand-held? Your spending budget?
