Bugged Canadian Coins? 354

tundra_man writes "CBC has an article about RFID type devices in Canadian coins found on US Contractors. From the article: 'Canadian coins containing tiny transmitters have mysteriously turned up in the pockets of at least three American contractors who visited Canada, says a branch of the U.S. Department of Defense.' The report did not indicate what kinds of coins were involved."

    For the life of me, I can't figure a reason that somebody would do this. Coins change hands quickly and RFID has a pretty limited range.

    Aside from:

    "Passing the coin to an unwitting contractor, particularly in strife-torn countries, could mark the person for kidnapping or assassination"

    But that doesn't seem practical in this case.

    Anybody make sense of this?

        I doubt this is intended as a coinage solution for Where's Willy [], the Canadian currency form of Where's George []. And the duration of the track of an individual depends on when the subject is expected to make another purchase. And it doesn't have to be very long to get useful, potentially compromising information, or just get the subject close enough to a reader wired to an explosive device.

        Scarier is the thought that such RF trackers are just the test run, gathering distribution data to see what will happen when they replace the RFID chips with tiny samples of Polonium-210 [] or other more deadly toxins.

      I also read the article and thought WTF.

      I seriously doubt anyone managed to mung currency and insert a real RFID unit.
      What I do think however is that in a small percentage of coins they resonate at the same frequency as an RFID which would appear as though they were magical.

      If you did infact hollow out a bit of a coin and replace some of the metal with an electronic bug the weight and bounce (striking against a piezo sensor) would cause such a difference any coin mech you inserted it into would reject it.

        Although it doesn't say what kind of coin was involved, I would guess it's almost certainly the two dollar [] coin. Mainly because I'd guess it's easy to pop out the center part of it that is a different metal. Even if you put plastic in there, the metal frame around it would make it feel pretty similar to a normal coin. There is also an advantage that when you cross the border you can't unload $1 and $2 coins. You can try to pawn off the small change to people who aren't paying attention (a problem in itself for northern states), but no one is going to take the big change - some won't take American dollar coins for that matter. Anyway that means they are more likely to keep the coin at least until they return to Canada.

        Also it's better if vending machines reject the coin. If you can't spend it in a soda machine you're going to just keep the coin, and probably try another.

        The Cryptic Article just says "transmitter" and goes on to speculate that it might be RFID. To look like an RFID without being one, the coin would not only have to resonate but also transmit a 128 bit number. Another problem is that the usual RFID wavelengths are way bigger than a coin.

    • Two reasons they might not change hands quickly:
      1) Canadian coins don't get unloaded as quickly in the US since not everyone is happy to accept them, so often those coins are the last you attempt to spend. (a minor factor, I admit).
      2) Everyone seems to end up with a pocketful of change at the end of the day that gets dumped in a pile. The pile just grows.

If the coins showed up on the person in a meeting with the contractor the next day you'd guess which members of the contractors team were present during the immoral activity.

      The only conclusion that I can come to is that someone is tracking these contractors to figure out who they are.

      These can't be general circulation coins. It's too expensive to put RFID in a coin, and there's no use for it. If the government was minting RFID coins, even as a test-run, there would be *some* mention of it *somewhere. If the government were doing it for legit purposes, they would own up to it after these reports. These coins must be being specially made.

      Why would you want to make them? I don't think you're really worried about the coin itself; you are worried about the person carrying the coins. You don't need to know where they are at any moment -- there is no infrastructure to track a single coin. You just want to correlate a person carrying these tagged coins on a regular basis with the source of the tagged coins. It's a kind of 'swarming' identification. If the person regularly has a number of tagged coins in their pocket 3 days out of the week, you know they must be one of the people interacting directly with the source. This person is part of the group of people you are trying to identify.

      Imagine a customs checkpoint on the border with thousands of people passing by every day. Suppose you know that there are some 50 contractors passing by there every day on their way to work in Canada. For whatever reason, you can't figure out who they are in any other way. But suppose you have access to the Canadian money supply inside the vending machines of the worksite. So you make sure that all of the Canadian money coming into the vending machine is tagged. You have a scanner inside the customs booth. Everyday, there are a number of cars where the driver has anywhere from 0-3 tagged coins. You know these guys must be getting tagged coins from the vending machine you control.

        My guess is that it was just a proof-of-concept for one of the vendors looking to sell the technology to someone (although obviously not to the contractors involved), therefore it was irrelevant as to whether the coins were disposed of shortly, or ever. If someone had developed a method of tracking the RFID tags over distances of 10s or 100s of meters, it would make tagging and following someone much easier.

      For the life of me, I can't figure a reason that somebody would do this. Coins change hands quickly and RFID has a pretty limited range.

      If you RTFA article closely you'll see that the souce told the press that transmitters were found in coins.

      Then (in paragraph 11) reporter notes that the type of transmitter was not disclosed. In paragraph 12 he starts speculating about RFID. The rest of the article (and possibly part of the preceeding section - along with the Slashdot headline) is based on the unfounded assumption that the transmitter IS an RFID-type device.

      Which strikes me as totally bogus.

      IMHO it's more likely that the "transmitter" found is a remotely-powered area audio bug, like "The Great Seal Bug", the martini fake olive bug, or the "diodes in the wall" bugs. Planted on a person it would bug his conversations and those around him until he spent it - hours or days later. (As you can imagine from the martini-olive bug, which is only useful while the spy is toting the martini, in some situations long-term bugging is an unnecessary bonus.)

      Such bugs can be simple: A shaped cavity with a flexible membrane over it is one way to do it - the cavity resonates, giving a strong reflection, while the sound modulates the cavity's effectiveness, AMing the reflection. Another is just to fasten a diode to something that can be vibrated by sound. The diode frequency-doubles the reflected signal or mixes two of them to produce the sum and difference frequencies (sorting the diode's reflection from most ordinary reflections) and the vibration of it along the line between the bug and the monitor phase-modulates the return with the local audio. No fancy circuitry or local power supplies necessary.

      I presume this one did involve at least a diode, or some semiconductor circuitry, since it was found in a radio scan - which is often done by looking for the frequency-multiplying and/or frequency mixing effect of diodes / semiconductor junctions. Finding a pure cavity resonator bug - or even identifying what it is when you have it - is a bitch.

      Bugging the audio at a conference, or the conversations of a contractor at work on classified projects, would be worth planting a bug on him and having it there for only a few hours. After that, if he "spends" it, so what? (At least until they are noticed and a way found to identify them BEFORE the conversations to be monitored.)

        My guess is that the bug was "planted" by the coin being placed directly in the contractor's pocket. This could occur when someone casually bumps into the contractor. As a result, the bug is hard to detect. Let's face it, if you found a coin in a random pocket, would you suspect that it's a bug?

An internally implanted chip would be nefarious, but a surface adhesion could be accidental. In the case of an internal implant, since the reading would be local, they would most likely be used to figure out the coming-and-goings of a few locations (i.e. stake out a building and see how many readings you get during certain hours), or perhaps to tell when somebody is NOT in their hotel room, so the place could be searched or laptop with sensitive information pilfered.

    Assuming that it was adhered, I could conceive how it could be accidental.

    Maybe its just something simple like they added chips to a small sample of coins in order to track them round the mint.

    Adding them to any processes after other coins are struck might allow them to see any bottlenecks in the factory line and therefore improve the flow of coins.

    Just an idea, seems more sensible than being used to track a person, because the chips probably had a low detection range, and coins change hands so quickly as other people have pointed out.
