That's a pretty clever idea. I like it! There is limited package space on items, this would allow producers to document a whole lot of info and allow consumers immediate access.
The idea actually comes from when I followed CJ Chivers (expert on weapons and war correspondent) A lot of his work is done by gathering spent munitions on the battlefield and then tracing it back to its source. The life of a weapon and munitions is usually well documented (and can go back decades!)
