The bar code is affixed to the back cover of the PP book.
If you have to take your PP out of the "cover" then you meant a passport holder/sleeve which you placed your PP into that was not originally part of the issued PP.
The scanner will not scan the barcode properly if it is behind one of these sleeves. One should always scan the passport bare, cover or pages to get a proper scan.
