Ironically, in 1997 I traveled with my APRS rig inside a 7.62mm ammo can. The kantronics kpc3 modem inside, a battery and a delorme yellow GPS mounted to the outside. The airport security was just happy to see the lights come on when I turned it on for them. No harm, no foul.... just a nerd going thru airport security.

The OP is referring to the DEF additive now required in diesel engines. You have to add DEF to a special tank and it is injected into the exhaust. The formula is ammonia based, hence his reference to "piss tank".
I was in München last fall. It looks like little arabia around Karlsplatz. I think the Germans are a little too friendly to their immigrants. Of course it doesn't help that the german birthrate has fallen below 1.8:1.
So Marko McFinn is living abroad and has an RFID chip embedded in his arm. How do the government officials in Finland know he has still got the chip and how do they know to stop his benefits? Afterall, there may not be any RFID readers in teh other country.
If no one scans it? OK, great, put an RFID chip in a person so they can receive State welfare while living outside the State. What difference does it make? The checks are direct deposited, who verifies the person's identity when they are/outside/ the country? Seems the simple solution is to not offer welfare to citizens who choose to not live in Finland.
