PDF417 Barcode Scanners are any type of scanner that can read the particular symbology known as PDF417. This is a two-dimensional barcode that is actually a combination of one-dimensional barcodes stacked on top of one another, resembling a snowed-out television set. PDF417 codes contain a lot more information in the same amount of space as a regular 1D barcode, and is often used as a summary for important documents or labels, such as tax forms or driver’s licenses. The biggest distinction is that a PDF417 code is a 2D barcode, although many of our imager-based PDF417 Barcode Scanners have the ability to read both 1D and 2D barcodes.
