Centering a barcode into a longtable

I try to center horizontally a barcode into my longtable, but I don’t success it.

Actually I’m trying to put the barcode juste before the (missing at the moment) page number (this page number is normally at the bottom of the page), all of that centered horizontally.

Here is what I have now :

And here is an MWE :
