Editing PDF417 (section)

== Features ==

In addition to features typical of two dimensional bar codes, PDF417's capabilities include:

* Linking. PDF417 symbols can link to other symbols which are scanned in sequence allowing even more data to be stored.
* User-specified dimensions. The user can decide how wide the narrowest vertical bar (X dimension) is, and how tall the rows are (Y dimension).
* Public domain format. Anyone can implement systems using this format without any [[license]].<ref name="iso2006">{{Citation | author= ISO/IEC | title= Information technology &ndash; Automatic identification and data capture techniques &ndash; PDF417 bar code symbology specification | year= 2006 | edition= second | id= ISO/IEC 15438:2006(E) | url= http://webstore.iec.ch/preview/info_isoiec15438%7Bed2.0%7Den.pdf | access-date= 2011-09-16 | archive-date= 2011-04-09 | archive-url= https://web.archive.org/web/20110409140736/http://webstore.iec.ch/preview/info_isoiec15438%7Bed2.0%7Den.pdf | url-status= dead }}</ref><ref name="iso2015">{{Citation | author = ISO/IEC | title= Information technology &ndash; Automatic identification and data capture techniques &ndash; PDF417 bar code symbology specification | year=2015 | edition= third | id= ISO/IEC 15438:2006(E) | url= https://webstore.iec.ch/en/publication/23356 | url-access=limited }}</ref>

The introduction of the ISO/IEC document states:<ref name="iso2006" />

{{ quote
| Manufacturers of bar code equipment and users of bar code technology require publicly available standard symbology specifications to which they can refer when developing equipment and application standards. It is the intent and understanding of ISO/IEC that the symbology presented in this International Standard is entirely in the public domain and free of all user restrictions, licences and fees.
