PDF417

PDF417 is a multi-row barcode symbology with high storage capacity and error-correction capabilities. It can be read by linear barcode readers, laser scanners, and 2d barcode scanners. PDF417 barcodes can store 1,108 bytes, 1,850 text characters, or 2,710 digits. A barcode is made up of 3 to 90 rows stacked into columns.

Each row consists of:

Depending on the encoding scheme, a codeword can contain:

MicroPDF417

MicroPDF47 is derived closely from the PDF417 specifications. It is designed for applications that require improved area efficiency without the maximum data capacity of PDF417. As a result it has a limited number symbol sizes with fixed Error Correction for each symbol size.

The following tables contain information for writing Micro PDF417 barcodes:
