end of the world currency

are we prepared for the end of the world we are prepared

just recently the government used the space on RFID chips present at currency to store wikipedia although all government ceased it was still possible to reconstruct lifesaving food n chemistry from the RFID currency that remained spread about the world

actually how the world ends is a funny story...

nothing to do with the idea, I'm just peevish. [dentworth, Oct 15 2009]


       So, the idea is to embed a lot of useful information in currency, in small chunks (64k is realistic).   

       This would be important in case the world loses the ability to read Wikipedia or other online or offline books, but still, by some miracle, retains the ability to decode RFID chips.

       I saw the zapped currency at the link then thought if they are putting RFID on currency it could carry valuable survival knowledge   

       "full faith and credit"   

       actually billions of people carry paper currency it could be valuable to load it with data that rescues the living   

       I actually do not know if currency has RFID or not   

       RFID reading is actually just a couple transistors a capacitor a resistor plus an antenna kind of like a 70s radio shack metal detector The linear data rate depends on the coding method   

       The government could cover their "bets" this way if there is an apocalyptic downside to their policies They could implement the survival currency prior to 2012

       It would be infinitely better to just print encyclopedia entries on the currency. That way, it would be fun to collect, you'd always have something to read with you (as long as you carry money), and we'd all have the chance to learn something.   

       And in case of the upcoming Zombie apocalypse, you don't need some complicated device to read the thing, either.

       What about microfiche? Short-sighted people could read it at least, if it was more than two point or so.

       Like [jutta] says, it needs to be more easily retrievable than this - if you absolutely have to use some kind of encryption method (rather than printing the plain text) perhaps a groove could be etched into the surface of coins or notes - holes being provided for rotational stability - and made playable by traditional record players - while these are not really in common usage these days, they can be operated without electricity - (a particularly useful feature come the IZA - Inevitable Zombie Apocalypse) and, for what it's worth, the overall method would provide a pretty nifty anti-fraud device as well.

       Unfortunately [zen], most traditional record players have a mechanism that automatically lifts and returns the arm beneath a certain radius, so unless you're also advocating 6" coins, this would not work very well. Nice idea though!

       There is a relatively easy solution to this, which is to cover banknotes in tiny print which is, however, visible if magnified, say through a dewdrop, glass or ice lens or goldfish bowl, assuming those technologies are available. Better still would be to make sure we know how to do stuff properly without relying on a complicated technological infrastructure.

[Rushes back in looking enthusiastic]

Day of the Triffids, of course! Everyone is blinded by the light from a meteor shower.

So, in order to mitigate this event, each bank note should be printed with one survival tip on it, in braille. In the event of strange lights in the sky and the takeover of the earth by our new, vegetable overlords, people would be able to exchange currency and survival tips in one fell swoop. There!
