[texhax] Printing "bar code" on document

    I saw this being done with MS Word and an add-on application. I
    would like to know if it can be done with LaTeX.

    I work in a small government office that issues permits. The permits
    are filled in and then printed out. We would like to print out the
    final permit with a bar-code that could later be scanned. Is there a
    package that does that?

there have been several articles in tugboat
about this:

 - Another Approach to Barcodes

 - The EAN barcodes by TeX

 - Generating barcodes with LuaTeX

there are also quite a few packages on ctan,
listed at
  http://www.ctan.org/topic/barcode

a somewhat more extensive list of possibilities
will result from entering "barcode" as a search
term at
  http://www.ctan.org/search.html

there are quite a few different "styles" of
barcodes, so knowing which one you need is the
first step.
