So, it never expires?
Kind of like your own, personal inventory number or tag?
We have that, it's called a Social Security Number, and it only expires when you die!
After seeing some of the stupid and underhanded things governments do, when they start seriously wanting something new and improved, and they give it a sweet sounding name (like "Patriot Act", that was anything but Patriotic) I am suspicious (NOT SUS!) of whatever it is they are trying to do, because it's all too often not for your good, but it's for the good of someone else's agenda, and often, it is in reality for your detriment!
Good for 8 years. Still, no cost.
