Portable Data File 417 (PDF 417) is a two-dimensional (2D) symbology that supports full ASCII, binary, and numeric data, and can encode foreign language character sets.
A traditional bar code is really just a key to a record in an external database that contains the useful information. A PDF, however, contains the useful information in it; it really is a "Portable Data File." The advantage to this is that access to a database is not necessary.
Error correction enables this bar code to make corrections for missing data due to a damaged or defaced label. Part of the label can actually be missing and the redundancy built into the PDF can still result in all the information encoded being readable. If the information cannot be read in its entirety, it provides no data at all.
PDF 417 Properties
The following properties are specific to the PDF 417.
PDF Security: Enables you to set the appropriate level of Error Correction Control (ECC), which determines how resistant the bar code is to destruction while still maintaining readability. The error correction levels range from 0 (no error) to 8 (maximum correction). Note that while higher ECC levels provide better error correction, they also increase the size of the bar code.
Rows/Columns: Allows you to specify the number of rows and columns which will comprise the bar code.
Truncated: Enables or disables truncated PDF symbols, where the PDF 417 generates a symbol with the right tow indicator and stop pattern replaced by a single width bar. This form of PDF 417 occupies less printed area than a standard symbol, but there is a slight degradation in decodability.
