Counterfeiting With High Resolution Inkjets
Makarand writes "Thanks to the availability of low cost high quality inkjet printers, crooks
are now able to
produce currency indistinguishable from the real
banknotes, at least under dim lighting conditions like that in a bar or a nightclub.
The term "digifeiters" is being coined for counterfeiters that use
cheap high-resolution printers to produce fake currency. Unlike costly color xerographic copiers that come inbuilt with features
to detect security details on banknotes and stop currency copying, no cheap printers
come with such feature. An anti-digifeiting system for cheaper printers may consist of printer driver software capable of recognizing data patterns indicating currencies of several countries." I wonder what GimpPrint would think of being forced to print or not print certain documents based on their contents.
Other recent articles about counterfeiting have mentioned a proprietary chemical mixture that removes a vast majority of the ink from printed currency, yet leaves the security strip, watermark and colored fibres intact. Bills treated in this manner will fool those colored markers that most places uses for confirmation. You get a stack of $5s, 'bleach' them and reprint them as $10s and you've doubled your money, print them as $20s and you're up to 4x, print them as $100s and you're at 20x. If you take bills as part of your job, double check that the watermark image is the same as the face printed on the bill, and that the value in the security strip matches as well.

From Anna's News Clippings
"A woman was charged $2.12 at a Diary Queen drive-through in Danville, Kentucky, and she was given $197.88 in change for her $200 bill. In case a clerk might not know that a $200 bill isn't legal tender, this taped-together bill was clearly marked as a 'moral reserve note' and featured George W. Bush's portrait. The White House picture on the bill's back has yard signs reading 'We like broccoli'and 'Rooms not for rent'. Police were notified as to the woman's presence shortly after she left. They do not consider the bill to be a counterfeit one."

The idea is to use a lower value note, say a one, then bleach the old ink off of it. Use your handy-dandy inkjet to print a twenty note on the paper that used to be a one. The one is well suited to false promotion because it doesn't have a florescent nylon strip that a bartender could positively verify the paper isn't a twenty.
Since all US notes are the same size, feel the same, and mostly look the same it's easy to fake. I know the French franc, prior to the Euro, used different sized paper for different values.
As a side note, if you've never seen the movie The Grifters there's a scene where John Cusack flashes a twenty at a bartender, asks for a beer, then pulls a slight-of-hand leaving a ten on the counter expecting the bartender to remember the twenty and give change as such.
I know folks in the US complain about the Monopoly-esque look of other currency, but it's a hell-of-a-lot tougher to copy, easier for the blind to judge denomination from size, and easier for visitors to manager. Put a dime in front of a visitor and ask him the worth of it. He can't. Nowhere does it say "ten cents" or "10 cents." It just say "One Dime."
Sorry for ranting.
This is a boring sig
To slow down counterfeit bills (about 1 in every 10,000 bills is a counterfeit). The US treasury will be releasing new bills this year. And every 7 years.
Having caught people using counterfeit bills from working in nightclubs and restaurants, it is starting to become a problem.

..like, for instance, Norwegian ones (see http://www.norgesbank.no/english/notes_and_coins/n otes.html for more on those) which has real securitymeasures like holograms and 'mother of pearl'-effect on it. Good luck trying to copy or scan that, 'cuz it plain can't be done without very, very specialised equipment. In fact, a while back I wrote up a short piece on Norwgian money for one of my american friends who were comming over to visit, and since he wondered how they have apperantly managed to scan it at http://www.norgesbank.no/english/notes_and_coins/c ounterfeit200kr.html , I gave them a call and asked - and was told that that picture was made out of a "number of scans at various angles blended together". For some reason they didn't want to give me any more details on how to achive that efect...
Sorry for not giving proper links, but I seem to have misplaced my little 'cheat-note' on how to write that bit of code...

It's just the US dollar that has been going down, and the others seem to be going up compared to US dollar.
Here, try comparing AU$ to CDN$. Neither is growing compared to the other.
Or, here's EURO compared to AU$.
Never underestimate the bandwidth of a 747 filled with CD-ROMs.
The solution of the euro notes are the diferent sizes, if you wipe out a 1,00 note it will be smaller then the 5,00 so you could not print it into the blanc note.
Also the diferent sizes makes it easier for blind people to recognize the value of the bills.

Actually, we have a great anti-counterfitting technology in all US currency that could easily replace the stupid pens with an electronic pen that costs just a few dollars, and would not mark or harm the bill at all. In addition to the color changing ink, the watermark, and the embedded plastic stripe (which the conspiracy theorists amoung us know the gub'mint uses to detect how much money you carry through the airport with remote sensors), all U.S. bills are printed with magnetic ink. Run a small recording head over the portrait of a real bill and you'll get a nice detectable signal from the background of the picture. Move the recording pick-up at a known speed and you can even determine the denomination from the frequency. And the inkjet printers will produce a bill that gives no response at all, no matter what paper it's printed on.

How does the plastic money handle?
:-)
Pretty much like paper currency. A plastic note feels pretty much like a fresh paper note in terms of properties; a little stiff and textured, but still very pliable. By feel, they are obviously not paper, but they don't feel like you're playing with a cheap plastic wrapper either.
The difference is that these properties don't really change as they get older. The notes get a few more creases in them, but they don't start to feel like tissuepaper like paper notes do.
The creases are about the only problem; it can be a bit of a pain to flatten them out, but on the whole, I gotta say I prefer them.
As a result, they last a lot longer in circulation - about 4 times longer. The down side is that they tend to tear catastophically; once a tear is started, it runs through the note fairly easily. However, it's very hard to start a tear in the first place (contrast with paper notes, which are easy to start a tear, but tend to tear slowly once started).
What exactly is in that window - some sort of hologram or other image?
Its a clear window, with an image in white ink in it. Each note has a different image. For example, the $10 note has a windmill. Its not a complex image - just a basic silhouette. There are some other security measures; microprinting, front/back alignment marks, that sort of thing. No RFID tags yet
I take it each denomination has its own color and size, but I think differing size would make it hard to carry around in your wallet.
Each note is the same height, but each larger denomination is slightly (7mm, IIRC) longer. The longest note ($100) fits easily in an average wallet. A $10 note (all that I have with me at the moment) is about the same height, but about 20mm shorter than standard US currency. That would make a $100 about the same size as a US banknote. (I don't have one with me to compare)
However, the real benefit is the colour. You look into a wallet stuffed with AUD bills, and you can tell if you have a little or a lot of money. See lots of pink, you've got lots of $5. See lots of green, you've got lots of $100. Single colour currency is one of the hardest thing I've had to get used to in the US. (that, plus tipping, and the fact that sales tax is never on the advertised price - but that's another story...)
