PDF417 is a 2d barcode (stacked symbology) used in a variety of applications, primarily transport, identification cards, and inventory management. PDF stands for Portable Data File and was developed by Symbol Technologies. PDF417 uses built-in error correction to ensure better readability.
PDF-417 is used for encoding large amounts of data, usually up to one or two-hundred characters are encoded in a single symbol.
The PDF417 symbology is mainly used in Europe and in the United States. The 2D barcode symbology is mostly utilized in the areas of logistic applications (especially in the automotive industry), transport systems (e.g. for shipping labels), identification (e.g. driver licenses, passports) and document management.
PDF417 is a 2D barcode symbology (two-dimensional barcode) with very high data density. A single PDF417 symbol can be imagined as multiple linear bar-codes (called "rows") stacked above each other. This is the reason why the PDF417 symbology is sometimes called a "stacked linear symbology". The overall shape of a PDF417 is rectangular. The size of the symbol can be modified by the user. The ratio of the widths of the bars (or spaces) to each other encode the information in a PDF417 symbol. For that reason the printing accuracy and a suitable printer resolution are important for high quality PDF417 symbols. Pure 2-D barcode symbologies like Data Matrix or QR Code encode the information in the presence of black or white dots at specific positions - and not by using bar:space ratios.
PDF 417 was developed 1991 by the company Symbol. In the year 2007 the company was acquired by Motorola.
PDF417 is also known under the names PDF-417, Portable Data File and PDF 417. The term Macro PDF (or Macro PDF417) is used when concatenating multiple PDF417 barcode symbols (see below - Structured Append).
