Barcode Toolbox for Mac

From Yin4Yang:

The function of these plug-ins is dual. On one side, you can create barcodes, and on the other side you can verify barcodes that are already in the artwork. The Illustrator version supports creation and verification of barcodes.The Acrobat version supports verification of barcodes.The plug-ins can also work in a demo mode, so that you see how the product works and you can check the quality of the generated barcodes. In the demo mode all barcode types can be used, but the codes can only contain the digits 0,1 and 2
