How can I put a barcode onto my product?

 I have just brought one i-phone. I think Apple is well ahead of rivals in building brand loyalty among its users. And as the barcode generator is very useful to our daily life. Maybe, you can manage to make a barcode generator by yourself for your phone, too. And I have just brought a barcode generator component so as to make a barcode generator by myself, and it works well. I-phone Barcode But, how can Idownload it to my computer to print it on my products Could you do me a favor? Thanks~~
