Jquery barcode plugin username and password

Question

Hi everybody!


 I want to use Jquery barcode plugin for my work. But I have a problem.
I don't know how can I change the source code that will be two field,
one field as username, one field as password.. between tabulator.


 So I want to a personal card generator with one barcode.
Is it possible? Because I did everything but doesn't work.

Please, help me!
