| Description |
PDF417, or Portable Data File 417, is a two-dimensional stacked bar code symbology capable of encoding over a kilobyte of data per label. This is important for applications where a bar code must be more than merely an identifier such as an index to reference a database.
The "portable data file" approach is well suited to applications where it is impractical to store item information in a database or where the database is not accessible when and where the item’s bar code is read. Because a PDF417 symbol can store so much data, item data such as the content of shipping manifest or equipment maintenance history can be carried on the item, without requiring access to a remote database.
