PDF417 is the most common 2D barcode, and can be used in a variety of applications including identification cards, shipping and inventory management systems. PDF417 offers more data storage than linear (1D) barcodes, up to 1,850 ASCII characters, and includes an Error Correction Code (ECC) which allows error-free reading even when a symbol has been partially lost or destroyed.

 Overview of LEADTOOLS PDF417 SDK Technology
- Uses Error Correction Code (ECC) to reconstruct damaged barcode symbols.
- Store up to 1,850 ASCII characters
- Can be combined with GS1-128 to create Composite Code C (CC-C) barcodes
Composite PDF417 Barcodes
PDF417 can be used in conjunction with GS1-128 to create GS1 Composite Code C (CC-C) barcodes. A GS1 Composite barcode is a group of two barcodes, one linear and one 2 dimensional. The linear barcode symbol usually contains the primary data, while the 2D barcode contains related supplementary data such as expiration date and product weight. CC-C can encode up to 2,361 digits of alphanumeric data.
LEADTOOLS also supports Composite Code A (CC-A) and Composite Code B (CC-B) barcodes which utilize various linear 1D symbols combined with a MicroPDF417 barcode.
