A 2D barcode scanner can interpret two-dimensional barcodes, which store data in two dimensions, rather than in just a series of black and white bars. 2D barcodes look like checkerboards or a series of traditional barcodes stacked atop one another. 2D barcode scanner use both CCD and Imaging technology to read barcodes. Additionally, our 2D scanners can be offered in corded and cordless form factors, or can be connected to iOS/Android smartphones and tablets. Whether you need a 2D scanner for the general purpose point of sale or for a rugged warehouse environment, call one of our experts to help you choose the right device. Quantity discounts are also available. If you’d like to generate your own 2D barcodes go to our 2D Barcode Generator, or check out our label selection to print your own 2D barcodes labels.
