Europe Adding RFID Tags to Euro Currency

An EETimes article a few days ago reports that the European Central Bank is planning to add RFID tags to euro bank notes. This would allow each bill to be tracked whenever it is used, and if the chip includes writable memory, to even record its own history.

    • Cost. Obviously mentioned in the article, the cost to place one of these chips in each bill is quite high ($.20-$1.00). Limited use only in large bills isn't helpful, since counterfeiting often involves bleaching smaller currency (eg $1.00 bills) and creating $50 or $100 bills.
    • Usability/strength. How many people wrinkle up their dollars and stuff them in their pockets/socks/etc? Would one of these transmitters hold up? How about if they were run through some sort of "demagnetizer"?
    • Other currencies. The article makes a point to note that this is aimed at preventing counterfeiting of what will soon be the most used currency in the world. But, unless other countries like the US do the same, it will just redirect counterfeiting efforts to other countries bills (like the US). This also includes the part mentioned in the article about someone demanding a ransom of unmarked bills, and how this would prevent that - well they'll just demand unmarked, US bills.

    The coil is 'read' by emmitting a radio signal and reading the reflected frequency from the coil. This makes the currency immune to all forms of defacing short of cutting the coil out of the currency or cutting it in half. If the bank was smart, the coil spans the entire currency so it's impossible to complete remove it. It can be read from up to twenty feet away.

So no, people aren't going to be able to magically read how much money is in your pocket.

      Almost right. An etched copper coil (or more likely aluminum, it's cheaper) can form the antenna, and also a small capacitor/inductor circuit to restrict the response to a narrow band of frequencies, but it can't store serial numbers. The cheapest way by far to do electronic serial numbers is to use a small IC containing the PROM plus interface circuitry. That does have to be connected to either several inches of wire (for the simplest antenna) or to an etched coil (for a more versatile antenna circuit). If you want to read it from several feet away, you probably must have the etched circuit, but the simple wire is enough to read it from a bill inserted into the machine, in a known orientation.

      I think antitheft tags use the etched circuit alone. This will echo a signal from a scanner several feet away to tell that a not-paid-for item is walking out the door. The tags aren't unique, but it's not necessary to know _which_ item. If anti-counterfeiting was the sole concern, etched circuits would be nearly as good as a chip-based circuit, and a whole lot cheaper. Each denomination would be tuned differently (so if you bleached a 1 Euro bill and re-printed it as a 100, the scanner would still see it as a 1). Scanners would start at about $50. The biggest counterfeiting threat lately has not been the few "professionals" (they get caught), but thousands of amateurs who get past that bad time before payday by a little work with a color scanner and printer -- it's not real good, but it will get past anyone who doesn't look too close or take time to really feel the paper, or hold it up to the light to check for watermarks and special threads woven in -- so there's about 1% chance a minimum wage clerk or a busy bartender will catch a funny 20 in the US. Any sort of RFID would stop these amateurs.

      Professional counterfeiters are rare and usually spend most of their lives in prison because anyone who can etch printing plates, print the money, and sell it, and doesn't take those skills to a legitimate job is either nuts or extraordinarily greedy. So they'll build the business up until the distribution end gets too big, someone gets caught, and turns in others. It might take the T-men a few years, but they persist until the printer is doing 10 to 20, if he's lucky and whatever mobsters are involved don't make sure he won't be around to testify against them.

      With or without chips, RFID wouldn't entirely put the pros out of business, but it would make things harder for most of them. Some already have "connections" wherever the paper for currency is made, and since the antenna, and chip if any, have to be added to the papermaking process, they'll get the RFID's too, but probably at double the cost. Those who somehow treat commercially available paper to make it pass for currency paper would be out of business until they figured out how to make the RFID, take two pieces of very thin paper, bond it together with the antenna inside, and still somehow make it look and feel right -- sounds like years of work to me... And if there are any that make their own currency paper, now they have to learn _another_ skill.

The countries that are allowed to join in, have to have a very stable currency. Only fluctuation within a very small band was allowed.

    > It will only catch the stupid drug user, john, etc., but what will the street find as a currency to replace it?

    Drugs are often used as a medium of exchange, particularly where street prostitution is involved. (e.g. pussy is sold for crack.)

    Now, given that your typical john doesn't have the capacity to make crack, we still have a supply problem, namely, where does John get his crack? He gets it from his dealer. But if the dealer won't take cash (or John doesn't want his trackable cash found on the dealer), what does John do?

    John uses legal, but heavily-taxed, drugs - alcohol and tobacco - as currency. Smugglers make a living by moving goods from low-tax to high-tax jurisdictions, providing supply to John through local merchants.

    As long as the corner store is stocked with smokes or booze (whether smuggled or not - smuggled smokes/booze simply afford the mob an additional profit opportunity at the start of the supply chain), John can legally purchase all the "tobaccscrip" or "boozescrip" he needs.

    If John's lucky, he's got a hooker who's an alcoholic nicotine freak. If John's not so lucky, she's a crackhead or pothead, and he'll have to exchange tobaccscrip and boozescrip for crack or pot at the local drug dealer, before purchasing any pussy.

    If the local mobster controls the flow of legal-but-smuggled goods (cigarettes, liquor), illegal goods (illegal drugs), and the prostitution, he can have an entire economy set up and running in no time.

    Finally, remember that in the underground economy, some currencies literally do grow on trees.

    John could, for instance, cut out the middlemen (and greatly drop his cost of pussy) in his drugs-for-pussy transactions by taking the additional risk associated with growing a plant or two of "hempscrip" in his back yard. Alternately, John could supply an organized-crime warez group with 0-day warez, pre-release MP3z, or various types of pr0n (whether legal or not).

    Currency as we know it evolved from barter. If barter is required to sustain the underground economy, the underground economy may become less efficient -- but that won't end the underground economy. It'll merely provide (like any inefficient market does) those in the market with more opportunities for profit.

    Argh! And I had better text to go with it, too. I should have saved a copy for just this moment. Alas, I'll just recap my concerns from my submission:

    1. Because of cost, this will be probably implemented first only in the larger denomination bills. (stated in the article)
    2. The security model is flawed. The authentication process encrypts the serial number, so without the algorithm you can't tell the bill's denomination. (You can track the bills by the unique encrypted number, irregardless if you know the algorithm).
    3. You put these two facts together, and the mere presence of an RFID bill in your pocket means you have at least ~USD$200. If you have 10 RFID bills, you've got at least $2000. Without bypassing the encryption, you can pick off the most worthwhile people to rob.
    4. Fortuantly, these are readable only at a short distance (~12 inches), but two antennas by the bathroom door will scan a whole lot of people.

  33. Legal tender for all debts by Wonko42 · · Score: 5, Interesting
    It always bugs me when merchants refuse to allow you to pay for something with certain bills. US currency is supposedly "Legal tender for all debts, public and private," yet merchants can somehow get away with refusing to accept them.

    It's understandable that 7-11 may not always have change for my $1.99 purchase that I pay for with a $100 bill, but as long as I'm willing to let them keep the change, it seems there is no legal way for them to refuse to accept my bill.

    Or have I missed something?
