Introduction to barcode PDF417
The PDF417 is a bi-dimensional barcode allowing to pack a large amount of data in a small space, saving more information than a “traditional” linear barcode. Encoding a full ASCII characterset, the barcode PDF417 can contain up to 2,700 characters. A PDF-417 barcode is arranged into columns, guarded by 5 black bars on each side, and each column is split into rows of clusters. Each cluster represents a codeword encoding a value which, taken with all the other values, defines the encoded data. This symbology includes error correction features (Reed Salomon) allowing to repair and read also damaged or incomplete barcodes.
