PDF 417, also known as Portable Data File 417, PDF 417 Truncated, and PDF 417 Compact, is a stacked linear two-dimensional barcode symbology that can be used to represent over 1000 alphanumeric characters in a single symbol. The PDF417 code word consists of four bars and four spaces, each of which can be one of three possible widths

pdf417 Barcode – Fonts, Software, Scanners and Applications
pdf417 Barcodes are used in many industries to encode more information than can be fit into a standard linear barcode. In fact, one pdf417 barcode can store up to 2 kilobytes of information in a space no larger than a few square millimeters. This makes them useful for storing complex information in a compact space.
The pdf417 symbology was invented by Symbol Technologies in 1991. It is named after the PDF (Portable Data File) – 417 characters that make up the code. The symbology is based on Reed Solomon error correction and has more than 1000 levels of error protection making it extremely reliable even when damaged or poorly printed. This makes it ideal for applications where durability is important such as ID cards, airplane boarding passes and driver’s licenses.
PDF417 Symbologies are usually scanned using laser scanners or 2D imaging scanners that can read stacked symbologies. A 2D Imaging Scanner is an imager similar to those found in digital cameras that uses a CCD array instead of film to capture

What is a PDF417 Barcode?
The PDF417 barcode has been around since 1991, when it was invented by Ynjiun P. Wang and patented by Symbol Technologies, Inc. A PDF417 barcode can be up to 1.1 inches tall by 3 inches long, which allows up to about 1,850 ASCII characters of information to be stored in a single symbol. The PDF417 barcode typically uses Reed-Solomon error correction for robustness when used in a supply chain environment.
The PDF417 barcode is a stacked linear symbol that can encode over a kilobyte of data per symbol. This symbology is also known as Compact PDF417, Truncated PDF417, MicroPDF417, and MacroPDF417.
The pdf417 barcode is a 2D (two-dimensional) stacked bar code that is used in many different applications. It can be used for storing large amounts of data in a small area. Each symbol can encode up to 1,850 bytes. In order to do this it uses Reed-Solomon error correction with the amount of correction being adjustable. This allows the barcode to be decoded even if it is damaged or dirty.
The pdf417 barcode was developed by Dr. Ynjiun P. Wang while he was working at Symbol Technologies Inc. and was patented in 1991 (US Patent
pdf417 Barcode is a 2-dimensional, high-density symbology capable of encoding over a kilobyte of data per symbol. It is used primarily in transportation and identification card applications.
The symbol is constructed with a pattern of bars and spaces that are either one or two modules wide. Each pattern represents a single codeword. A pdf417 symbol can have from 3 to 90 rows, each of which may contain from 1 to 30 codewords.
The information is encoded in codewords consisting of bars and spaces. The total number of bars or spaces in each row must be a multiple of 17 modules plus the stop pattern (total width), which is 9 modules wide. The minimum width for the entire symbol is 51X (X = the module width).
