this information is very.... useless...

because the information is printed into the stamper to make the blanks. And 
when a manufacturer sells its stampers to another on, or a third buys them on 
the 'second hand' or 'grey market', the ATIP information has nothing to do 
with the real manufacturer. There are even stampers, discarded by the 
dedicated vendor, because of bad quality, that are used by cheapo east asian 
manufacturers.
