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.

The I2 molecules have *just* the right diameter to fit inside the helix of a starch polymer perfectly.

      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.

      When I first discovered it I was working with the head typesetter. We couldn't figure out what this strange very light interference pattern on every printout from the color copier (which had it's own RIP) was. It was the same regardless of whether we were printing or copying, and regardless of the content, and it was an identical pattern on every sheet. That particular copier (as far as we could tell) didn't have any moving parts that synced with the page ends well enough for it to be a physical problem. And if we put the machine into black and white mode it went away.

      It took several weeks of me badgering the service guy, and 3 service calls for 'Image Quality', before he finally admitted what it was.

      DANVILLE, Ky. -- It started out with a blizzard and now a Dairy Queen in Danville is getting an avalanche of attention.

      A woman who paid for her food with a fake $200 bill Sunday left with plenty of change. The bill had a picture of George W. Bush on the front and oil rigs on the back. "That's the talk of the town," Danville resident Joseph Bourne said. "It's got to be one of those dumb blonde stories."

      Added fellow resident Drew Hammond: "It's the kind of news I like to hear out of my own hometown. Usually things don't happen of great significance here. It gets a lot of attention."

      The 18-year-old employee has offered to refund the store. Her manager, Mike Tracy, tried to be supportive, and said that she probably was just too busy to notice the mistake.

      "We try to do things as quick as possible here," Tracy said.

      At least he's being a good sport about it. The restaurant is now distributing coupons on the backs of fake $200 bills.

      "We're going to play off this advertising a little bit and try to think of it as something positive," Tracy said.

      Local law enforcement said that the joke became a crime when the woman took off with all that change.

      "When the woman received the money and left with it, the joke ceased," Danville police officer Bob Williamson said.

      Still, because there's no such thing as a $200 bill, the woman, if caught, couldn't even face federal counterfeit charges. From here

    They copy the bills, but some do stuff to make the copied bills unusable, like make a perfect copy of a bill but make the entire page hot pink. The Ricoh printers we had at my last job did that. Other copiers make the copy, but insert a code number somewhere on the bill unbeknownst to the counterfeiter. When the bill makes its way to the Secret Service, they find the code, contact the company, and find out where that copier is located, which speeds up the investigation quite a bit. IIRC, a few years back they nailed some idiot Cornell students this way. Unfortunately I can't find the story on Google, and I don't quite remember where I heard it-- possibly from one of the Discovery Channel or History Channel documentaries concerning the U.S. Mint or the Secret Service or counterfeiting.

    Firstly, silver coinage is very much out there, even to the point that a handful of silver Kennedy half dollars can be found in a single deposit from a department store (there was even a Franklin half in one batch). Perhaps people just don't notice silver coinage even in high-volume retail ... but then again, in handling coin, I soon learned to listen to the distinctive sound of silver tinging against the cupro-nickel normal coinage in the sealed bags. (There was one false alarm that turned out to be Eisenhower dollars.)

    Secondly, fake twenty dollar (US$20) bills are being easily passed along in bars ... I can only conclude that this is because that these are generally places where the lighting is more dim, lots of small transactions take place, and frankly, where the environment is busy and loud. Counterfeit 20s (and some 10s) showed time and time again in their deposits. (It was particularly amusing to contact the customer about the debit, since it seems some of them expect the bank to simply replace the bill with a real one.)

    It could also be that the criminal element that does the counterfeiting is native to the bar-going crowd.

    I have inspected these fake 20s in some detail. I noted right off the bat the "obvious" difference: the overall hue of the bill is off just enough to be suspicious. It is a little darker, and either slightly more yellow, brown and even a tiny bit purple. So it is easy for me to believe that these bills can be passed off in a darker environment.

    The texture of the bills was OK, surprisingly. It could be that the paper was run through a washing and/or brushing mechanism to more simulate the cloth-y feel of a real bill. As for the microprinting ... of course, it was a washed out line and that more than anything told me it was counterfeit.

    P.S. A final note about hue ... bills go through a lot, and you can't just go by the hue. I've seen bills that have been dyed ... light green, dark purple, things like that. It happens.

The old ones will still be accepted, and if they're easier to forge, why wouldn't I just forge one of those? Frequently changing their design won't really counter counterfeiting (heh, no pun intended there).
