Inspired by Hippo's idea to keep
counterfitting down.
Essentially, this is a bank note fitted with
an oled (plastic LEDs) screen. A plastic
strip in the weave would house the chip
and the power supply. (They do make
flexable ultrathin batteries and come to
think of it rollable solar
cells.)
Oleds are good because they can be
printed on a pliable surface and use little
power. Only one company would make
the hardware for the chip and power
supply. And it would be easier to track
down the maker of such hardware rather
than someone with a high quality printer.
The money could also keep track of its
own shelf life and shut down when you
need to exchange it for fresh currency at
a
bank.
Also the money would glow in the dark
with vibrant colors.

I would like mine to display 10 pounds when I receive it in change, then display 100 pounds when I spend it. |
|
| |
Ha. No only the pictures will be
moving; that or the numbers could
change colors actively. |
|
| |
Not exactly, because the oled is still a
printed plastic as long as the number is
intact and you still have the strip to fall
back on for a number of features. If it
malfunctions, its time is up and you will
probably be instructed to go to the
bank and get a new one. Imagine also
in situations of changeovers like in the
case of the Euro. |

Also, it would glow in the dark with
vibrant colors. |
|
| |
Hmm, should put that in the body. |
|
| |
With a little 'help! I'm being mugged!' button on it which renders it worthless. |
|
| |
It'll be hacked before its first day of existence has completed. |
|
| |
//Also, it would glow in the dark with vibrant colors.// You could blind would-be muggers. That or allow them to find your money faster. |
|
| |
Irrelevant if it is hacked, the fact that it
can be used to make the money glow in
the dark. Hacking the picture, might
make the money worthless at the most. |
|
| |
Only if you could tell it was hacked. |
|
| |
Yes, but if someone were to put into the
picture, 'eat more cheese' it would be
like someone taking a magic marker to
a regular bill. If you didn't notice the
superficial change, then you wouldn't
care because the number would still be
printed. |
|
| |
I thought oleds for a credit card might
have already been baked, so I didn't
post that. Actually, oleds need only be
printed, that's the boon to the
technology. |

Why not a photovoltaic cell which uses UV light, which is already used to test for counterfeits? That way, you will hold it under the lamp, and not only will the hidden characters appear, but the {Queen/President/Etc.} will wave. |
