#-- # Copyright 2012 Michael Chaney Consulting Corporation # # Released under the terms of the MIT License or the GNU # General Public License, v. 2 #++ RELEASE VERSION This is an implementation of 1D barcodes in pure Ruby. Code currently works to generate and decode Code 128, Code 3 of 9, Code 93, Code 11, Codabar, Interleaved 2 of 5 (I 2/5), COOP 2 of 5, Matrix 2 of 5, Industrial 2 of 5, IATA 2 of 5, PostNet, Plessey, MSI (Modified Plessey), EAN-13, EAN-8, UPC-A, UPC-E, UPC Supplemental 2, and UPC Supplemental 5 symbologies. This is a pretty complete set of 1D symbologies and most or all other common symbologies are based on one of the above. As of the 2000s most bar code advancement is taking place in the 2D realm so it's unlikely that anything more will come about. Additionally, Code 128 is general purpose and sufficiently compact and robust enough to cover any application. I recommend any new application using 1D barcodes use Code 128. Strictly numeric data might also use Interleaved 2 of 5. Of course, 2D barcodes are common now but 1D codes still have a huge installed base of readers and are generally easier to deal with. Contact Michael Chaney Consulting Corporation for commercial support for this code: firstname.lastname@example.org I also have a fairly complete Perl implementation at: https://github.com/mdchaney/barcodes I believe those work fine, but consider it legacy code.
