PDF 417 Bar code Scanner

"PDF 417 Bar code Scanner" are any type of scanner that can read the particular symbology known as PDF 417. This is a two-dimensional bar code that is actually a bunch of one-dimensional bar codes stacked on top of one another, resembling a snowed-out television set. Clearly, this code can contain a lot more information in the same amount of space as a regular 1-D code, and it is therefore often used as a kind of summary for important documents or labels (e.g. very common on tax forms and driver's licenses). The important distinction in the bar coding industry stems from the fact that PDF 417 is a 2-D code, but many manufacturers offer a 1-D type scanner that is capable of reading PDF 417. Pretty much all two-dimensional scanners (or, imagers) can read PDF 417 and one-dimensional bar codes.
