Well I call bull shit on this. If you want to break it down bar code is a binary counter with 4 widths of bars. You count the widths like in a pulse width in a digital devise. The bar codes has the same number you can read at the bottom of it, just in computer "words." There is not always even one 6 in the code.
I won't even both with your religous talk, it's like that kid that keeps saying "are we there yet" don't matter what you say to the kid. The kid just keeps saying the same thing.
So in short, you should "research it yourself" before you talk.
