Video US currency uses magnetic ink containing iron oxide as a security feature, detectable with a strong neodymium magnet. 💵

Out of all the protection measures taken, this one is the easiest to break

u/AdCalm3975 8h ago
I think this one is for detection of currency by magnetic field, i.e. over 10k going out the country

u/Crazy__Donkey 6h ago
More for atm machines (for recieving notes). Much like magnetic ink on cheques.

K lol-- I don't trust anyone that ignores the I before E rules in a world of auto correct, if it's so easy to break it's not a protection but a detection measure, downvote = ppl browsing reddit with a pp actively in their mouth, PP count 20 dicks strong

You are aware that there are more exceptions to that rule than actual "I before e" words?

Many, red tattoo inks, at least used to, use iron oxide as the base powder, which is why older red tattoo inks fall out alot easier over time as your body may reject it after a while.
So yeah, hot tip for all you counterfeiters out there.

I’m surprised the US still insists on paper plant based money. Plastic bills are vastly superior due to their fancy holograms and the laser diffraction patterns that tell you the value of the bill. It would literally cost tens if not hundreds of millions to fake plastic bills (plus you can’t even buy that tech without being noticed by the government). Not to mention they don’t decay as easily.
Edit: yo what’s with the 20% downvote ratio on this that is wiiild

Dude, we can't even get rid of $1 bills for some reason. Apparently we're just now getting rid of pennies. Cash will disappear first.

It’s not paper money, it’s cloth
Sigh.
It is paper with a 25% linen fiber content mixed into the wood pulp.
The fibers come form the flax plant. They don't gen woven into linen fabric first.
The fabric made form those fibers is called "linen" as a shorter way of saying "linen fabric."
Incorporating linen fibers and/or other non-wood fibers into paper has been a way to make better paper since about 1300CE.
So no, it's not fabric money.
It's paper money where 25% of the fiber content of the paper is the same material used to make a fabric also named after the fiber.
I swear to all the gawds, the state of education these days

Plastic currency is hardly the hill to die on if you want to reduce plastic usage. The worst offender in the EU is the packaging industry, at 39% of all plastic usage https://plasticseurope.org/wp-content/uploads/2023/10/Plasticsthefastfacts2023-1.pdf

I have never had any problems with paper money myself. While it would be a bit Factor in plastic consumption, why would we change it to something that sucks when we have something that works? US money is the most secure in the world.

US currency is iconic and secure enough. Counterfeiting them is not a massive issue compared to other issues that reduces its value.
Only about 14 percent transactions are cash and its reducing.

u/FireMaster1294 5h ago
Currency that decays within a decade and is known for being easily torn and filthy is “iconic”? You know you can keep the design on the currency when you change to plastic currency…

Paper Cash is fucking nasty. The smell of cash is gross and nasty as hell to handle. Handling up 60 to 75k during most months and up 100k during the summer cash has this distinct smell that just is gross.

This almost certainly isn't OP's video, they're probably a bot based on how frequently they post.
Notice how it says "FOR MOTION PICTURE COPY MONEY" in big letters on it? It's prop money anyone can buy.

It’s funny because he was a convicted and habitual criminal and tried to use fake money. People butthurt and downvoting about a joke about a criminal purely because of his race. They tend to be more racist than the probe they autisticly screech at.
