They have become easier to use than ever before. Long gone are the days of dealing with decoder boxes and multiple cables. Simply plug the cable into the scanner and PC and you're up and running! One of the most important concerns when choosing a suitable scanner is the type of scan engine it has. There are 3 main types of scan engines:
The laser scanner is the most well-known scanner type. It uses a red diode laser to read the reflectance of the black and white spaces in a barcode. Laser scanners are only able to read standard linear (1D) barcodes Linear imager scanners are similar to lasers in that they also only read 1D barcodes. But instead of reading reflected light from the laser, they take a picture of the barcode. Like linear imagers, full 2D imagers also capture an image to analyze. But compared to the linear only devices, these scanners can read any type of barcode. 1D, stacked, and 2D barcodes are all supported by a 2D imager. Another advantage these images have is that the orientation of the barcode isn't important when reading. With lasers and linear imagers, you have to line up the indicator horizontally across the barcode. A 2D imager is taking a more detailed image and is more intelligent, so you can read a code in any direction
Most of us are familiar with the basic gun-style and in-counter scanners from retail and grocery stores. There are 5 main form factors for scanners, and each has advantages depending on your application and how you'll use the scanner.
These are by far the most common form that scanners come in and are very easy to operate. Simply aim the scanner at the barcode and pull the trigger. Presentation scanners are designed to sit on a counter-top and don't need to be picked up or held. These scanners are made for hands-free scanning and will not require triggering to read.
