Barcode The Barcode policy feature enables you to track physical copies of a document by creating a unique identifier value for a document and inserting a bar code image of that value in the document. By default, bar codes are compliant with the common Code 39 standard (ANSI/AIM BC1-1995, Code 39), and you can plug in other bar code providers by using the policies object model.
The barcode feature has been removed in SP 2013 (beta 2) and most likely in the final release. If you plan to implement this feature in SP 2010, be warned that once you upgrade to SP 2013 your feature using barcode will not work. The reason this feature was dropped in SP 2013 is because of low adoption.
For a list of features discontinued in SP 2013 see below article.
Barcode in SharePoint is part of Information Policy Management, that can be applied to content types or document library.

The limitation, currently it generates the value automatically and doesn't provide a way to accept value from user input or barcode reader.
However you can extend this feature by creating component that will change the barcode value programmatically.
