Sometimes before I go to bed I think a lot. And last night, one of the things that came to mind was this picture. It apparently shows a foolproof way to cheat the US postal service. (And other postal services I assume.) Now, I know little about the system, but I know enough to think that this is either possible or at least partially passable. But I’m a problem fixer myself.
I believe that I’ve figured out a way to make sure that this doesn’t happen again. All the postal service has to do is stamp mail with the originating zip code or office number. That way if you’re in California and you’re trying to mail a package to Washington, D.C. for free, it’ll get stopped before it even leaves the state. It’s not as easy as just adding an extra ink stamp though, because those are pretty easy to duplicate. It might have to be a “QR code”-like sticker or something like that. Something one doesn’t come by easily. Or if it must be an ink stamp, perhaps it can be on anti-fraudulent paper or the like.
Anyways, that’s my suggestion. Feel free to tear it apart if you must.
