![]() The scanner is smart enough to align it on its own, which means less aiming before taking a reading. You don’t need to worry about the orientation of the barcode while taking a reading. That includes stacked, 2D, and 1D barcodes. The third type are 2D area imagers, which are able to read all types of barcodes. At the same time, they have comparable range and cost to a basic laser scanner. Linear scanners tend to perform better that laser scanners for reading damaged codes, or codes that have been printed poorly. The second type is a linear image scanner, which takes a picture instead of reading with lasers. But for greater range, you often need reflective labeling. ![]() Though they can only read 1D barcodes, they’re also among the cheapest options out there. ![]() This type uses a simple red diode to measure the blank spaces between barcode bars. Among those three, laser is the single most common. The three most common types of scan engines are laser, linear, and 2D area imagers.
