Printing Ultra-Thin Circuits Into Banknotes Could Give Electronic Security to Paper Currency

A human spammer, or an incredibly skilled chatbot? Either way, the effort represented is astonishing. How common is this CAPTCHA method? Anyway, if the solution to an Explorer problem is installing a new browser, wouldn't the solution to a Windows problem be installing a new OS? (I mean, that's certainly my sentiment, but.)

On the topic, this is clearly in a very early state. For instance, the circuits could be run by the same charge as the passive array of an RFID chip, but you'd still need to pick it up somehow, and the array on an RFID chip is the bulky part. There's also no mention of the potential cost of the authentication circuit or its durability. It just seems like this information is too early to be useful, like a press release of a physicist's napkin scribblings on an upcoming paper.

HEY POPSCI!!! YOUR INVASIVE ADVERTISING ON THIS SITE IS MORE IRRITATING THAN THE SPAM WAS!!! COMBINED WITH ALL OF THE ERECTION ADVERTISING IN THE MAGAZINES NOW I'M SERIOUSLY CONSIDERING A DIFFERENT SCIENCE SUBSCRIPTION!!!

Christ, I hate that iRobot ad to death. Wheel scrolling doesn't work over flash apps in Chrome, because the app captures the scroll input, and I don't have scroll bars enabled, which means that when that iRobot ... *thing* drops down, taking up more screen space than my netbook *has,* it's a pain in the ass to find my way up to the little X, which is always above the edge of the screen. I just had it happen while I was flagging the spambot above. = )

What's the use? This technology turns paper money into a type of debit card or electronic document, so why not just operate with cards and electronic accounts? And most of the money in existence is debt or derivatives anyway - empty bets and promises not backed by underlying wealth. With this technology it will be harder for regular crooks to counterfeit money, but the crooks on Wall Street who create most of the fake money in existence, won't be fazed.

Seems like a huge waste of time, money and manpower. The overall trend is cashless, no paper,no plastic,nothjing but your hand or forehead, thats where they will end up putting the "chip".That will eliminate any possibility of fraud or counterfitting.The "readers" also detect body heat so one can't use a severed body part.Please report on that available technology and where it is going, and don't say it's not available. It most certainly is and the Army has been using since the 80's

There are ATM's now that are starting to dispense Gold - I personally use my credit/debit card... if someone stole my wallet and spent my money, it's gone forever... but my credit/debit card is at least insured.

Then again, we could go back to the barter system - I'll trade you 3-goats for your 1-cow, sound good? *shakes*

@dirk, the captcha is easy unless you have a problem typing so stop complaining, the advertising could be less agressive

Why bother, cash is only necessary when one wants to make transactions under the radar and avoid taxes these days. It would almost make sense to start phasing it out, starting with the 100 then the 50 and eventually the 20.

By phasing out cash, money is kept in banks at all times where it can be lent and circulated. This would increase the velocity of money and hopefully help the economy without adding to inflation.

You also eliminate the risk of loosing money. I mean physically loosing it.

Whaaaa? How does Wallstreet make fake money?

Are you claiming that Wallstreet causes price inflation or monetary inflation or devaluation of currency?

Inquiring minds would like to know...

@ZOMG_ZOMBIES
Yes, that's correct - Wall Street is creating devaluation in currency, as well as creating other forms of fake money that's not backed by underlying wealth, like derivatives, swaps and securities (valued at around $700+ trillion) and of course debt (the total amount is anyone's guess). These derivatives are used as an instrument of trade and speculation, so they are a form of currency. Of course, regular people don't buy their bread in Credit Default Swaps, but here's how they're linked to "normal currency". The problem is, on the upside of the credit/derivative bubble, the currency-denominated money supply (like M2,M3) goes up as well, because more trades and speculations are made with these empty securities (credit default swaps or CDOs for example). But when the bubble bursts, i.e. people walk away from their mortgage contracts, or a country defaults, enormous amounts of debt are wiped away along with all the fake securities based on these debts. This graphic:

shows how the money supply rapidly expands along with the credit bubble. After the burst however:

Much of the broad money supply (M3,MZM) evaporated. That's where "quantitative easing" (printing money) comes in. In order to save the banks from implosion and make sure they have enough liquidity (available "money") to continue business, the Fed expands the narrow money supply (M1) to make up for the shrinkage in M3 (which the FED stopped publishing in 2006). So after 2008, when a small part of the excess debt evaporated, the Fed printed up about $2+ trillion to make up for the loss in M3. Bernanke is contemplating another $4 trillion; according to Krugman, $8-10 trillion is needed to make up for all the upcoming shrinkage in M3. The actual number could be as high as $30 trillion to make up for all the bad debt that banks hold today. The catch here, is that the FED is not a government institution. Rather, it's owned by Wall Street banks and financial firms, which have a direct interest in being bailed out, and in expanding M1. As M1 is inflated, the dollar will start to lose ground on the international markets and will eventually flood back into the US, causing a dollar hyperinflation (explained by Peter Schiff), and a simultaneous credit deflation (explained by Steve Keen and Nicole Foss). I hope this helps.

This is about the most useless bit of tech. All it will take to make them counterfeit is a high-energy pulse. FZZZZT! What a waste of tax-payer dollars.

No need to rearrange your entire online life like installing a new browser or operating system because of ads and other annoying things in websites. I use a local filtering proxy that filters out most of the junk from websites before it reaches my browser. I use privoxy and it works well and its free.

i am student i would like to use this invention as a graduation project so please i need help as more detials and information am really apprecaiate this idea and love it and i decided to implemented
is it complicated ???
so can u help me to implemented ? ^_^
