Linear imagers read 1D, or linear, barcodes and are also known as CCD scanners, CCD LR (long range) scanners, and full array imagers. Their scan engines have no moving parts, which means a linear imager barcode scanner is typically more durable than a laser barcode scanner. Linear imager barcode scanners are better for reading poorly printed or damaged barcodes as well as barcodes under plastic film or covering, making them ideal for a variety of applications including inventory, shipping, receiving, and retail.
