WEAPONS: The RFID zapper
Radio frequency IDs (RFIDs), small electronic chips that share information when scanned, are rapidly becoming an essential part of global supply management. In order to correctly route and track items from inception to purchase, these chips are attached to packaging and increasingly the products themselves.
The intentional disabling of these chips can cause supply chain disruption. The best method is to HERF (high energy radio frequency, usually microwaves) the chips using a small transmitter (read about high power home made microwave weapons for herfing). The German branch (privacy activists) of the global guerrilla innovation network has developed a simple solution that converts a standard film camera into a short range RFID zapper. This system:
"...copies the microwave-oven-method, but in a much smaller scale. It generates a strong electromagnetic field with a coil, which should be placed as near to the target-RFID-Tag as possible. The RFID-Tag then will recive a strong shock of energy comparable with an EMP and some part of it will blow, most likely the capacitator, thus deactivating the chip forever.
To keep the costs of the RFID-Zapper as low as possible, we decided to modify the electric component of a singe-use-camera with flashlight, as can be found almost everywhere. The coil is made from varnished wire and placed inside the camera exactly where the film has been.

Then the coil is soldered between the cameras electronic and its flashlight. Last but not least most single-use-cameras will require some kind of switch to be build into them, since their activating-mechanism usually is to small and primitive. Once the switch is connected and tested, the camera can be closed again and henceforth will serve as a RFID-Zapper, destroying RFID-Tags with the power of ordinary batteries."
I don't understand how close-range disabling of an RFID chip is going to cause "supply chain chaos". Each item's RFID would have to be taken out one at a time.
The only way to cause larger disruption would be either (a) a device that would disable at a medium range, a large enough distance to take out all RFIDs in, say, a shipyard or warehouse; (b) something to disable the receivers.
For that medium-range disabling I suspect the energy needed would be pretty significant, and the device large and powerful. As for disabling the receivers, you might as well just take out all the computers in a shipyard, which would cause even more chaos! But again, that would probably require a very large jolt.
I imagine the best use of those camera-based devices is for shoplifters to zap the RFID tags on merchandise. Now there's a threat! ;-)))

I think you need to look downstream on the trend lines for RFID use(particularly in combination with GPS chips) to fully grasp the impact of this. Larger and more powerful devices are in development, this is merely a device that can be made right now that fits in a pocket and can be used against much more than just RFID chips.
Posted by: John Robb | Wednesday, 04 January 2006 at 11:06 AM
Yup, bigger devices will be needed to go beyond petty theft. But how big?
I don't know the exact physics, but I suspect the power of the jolt varies inversely with the square of the distance, like electromagnetic radiation, gravity, electrical fields, etc. The reason is geometric. See...
http://hyperphysics.phy-astr.gsu.edu/hbase/forces/isq.html
So, if the power needed to work at, say, 1 foot is p, then you need 1,000,000*p to work at 1000 feet. So, you're talking some pretty big, powerful apparatus.
And yes, if you can kill the RFIDs, you'll also probably get all computers, cell phones, digital cameras, electronic vehicle controllers and IPods.
Kill all IPods -- now there's a threat ;-)))

If you want to disrupt a supply chain, and you can get close enough to RFID tags to zap them, why not just modify an RFID tag to trigger a small bomb when scanned, and plant that on the pallet? You know it will go off at a key location: the RFID scanning station.

'Shaping Things' is Bruce Sterling's take on this and the trajectory we are in, going thru these waves of technos, both logical and ill. In an interview with Business Week he mentions the immediacy of the use of arphids in combat.

if you want info on a medium scale personal emp device checkout the ibomb at eiu.org
Posted by: katie | Wednesday, 04 January 2006 at 09:14 PM
The way you disrupt a supply chain with this device is not to take out the RFID of each item, but the RFID of the pallet or crate the item is in. this is much easier for one, and two if thirty pallets have their tags ruined thats thirty pallets sitting in a warehouse taking up space while also taking up man hours to hunt down where they go. also if you wanted to do more damage, it is possible to build an EMP device that fits in a backpage that can clear a ten foot radius. there are basic plans (though they leave a few things out) in a book i think called "electronic projects for evil geniouses". They sell the book in most Borders.

You get the same EMP efect if you blow up a nuke bomb and you get better range. Lets kill all the RFID tags!!!

Nuke them from orbit. It's the only way to be sure.

I disable RFID chips with my heinous farts. Their massive sonic boom can shatter glass.

I still like the shoplifting idea best. If the EMP-in-a-camera device gets around, then RFID in retail becomes useless, which might kill the whole thing. RFID and chips would lose a major portion of their market, not to mention trust factor in general.
Another idea is to drop a couple of those babies at some well-chosen tollgates on the NYS Thruway, Mass Pike or whatever at 5:00 PM. The resulting traffic jam would set western civilization back at least 15 years!

Don't forget: all new U.S. passports will contain RFIDs which can be read at a distance, thus offering opportunities to ID thieves and terrorists looking for a good target ... perhaps a pre-vacation zapping would make citizens safer.
On a related topic, I described an explosive-compressed EMP weapon two novels ago in Slatewiper.
Posted by: Lewis Perdue | Thursday, 05 January 2006 at 10:33 AM
Also not to be forgotten: because it's not all that hard to build a directed, explosively compressed EMP weapon, it would also be possible to bring down a fly-by-wire commercial aircraft such as the Airbus and newer Boeings.

I think when they say disrupt the supply chain, they mean disable a rfid tag so you can steal stuff.
Posted by: blah blah | Thursday, 05 January 2006 at 11:04 AM
thats pretty sweet! i was wondering. do i have to flash. or does it just have to be near it?
Posted by: miscblogger | Thursday, 05 January 2006 at 02:50 PM
You'd have to charge the flash, possibly fully. It'll be the capacitor that would produce the necessary energy to disable the RFIDs. I'd imagine you'd have to push the "capture" button, which would release the stored charge, bypassing the flash into the wiring he was refering to.
I believe.

Most stores will not allow the use of a camera on their premises. Not that they would think it is repurposed as a RFID zapper, their concerns are that illicit activity or unlawful marketing on the part of the store is being documented.

I'm a little out of my element here, but I get the sense John's trying to get us to think of the longer term implications - not only of RFID, but the capacity to disrupt the network/nodes that RFID relies on.
Consider (http://en.wikipedia.org/wiki/Metcalf%27s_Law
Metcalfe's Law, which posits the value of a network increases exponentially as nodes are added. This means that each node has a gradually increasing value itself, and with that increase in value comes the proportional increase in risk.
By the time RFID networks are ubiquitous and entrenched enough to morph into a public utility (i.e., Internet, GPS, weather, etc), devices like this will post measurable threats to the stability of interdependent social and economic systems.
John, you have a moment to offer a sanity-check on my interpretation?

Speaking for the Urban Youth, this CERTAINLY has applications for shoplifting.

Too bad, really. I rather began to enjoy the old girl.
Posted by: Sean Moriva | Tuesday, 17 January 2006 at 10:04 PM
The most current/appropriate use of this device should be to disable the RFID chipped US Passports, as previously posted..."pre-vacation zapping would make citizens safer"
Posted by: m4e | Friday, 27 January 2006 at 06:49 PM
what about confounding the supply chains by adding extra tags to the packaging and pallets?
if one knows where exactly the tag is it's antennae could be cut with a razor or chip crushed with needle nose pliers. maybe?
what's most needed more than shoplifting is a legal/medical/technical excuse from taking the subdermal implant when it becomes "mandatory", leaving the majority who don't care to their own arphid devices. you naughty boys at this website could make some friends by helping some underground christians who may have all the free food come crunch time.
or just put yer passport in the microwave at 7-11 on yer way to the airport.

A few considerations on RFID. Stores like Walmart may think it is neat to scan the whole cart and take inventory. So if I think a price is wrong what do I do? Look at the receipt after I pay to argue the point, only to go to a long line at customer service because the next person is now being checked out? After I purchase the item is the tag de-activated? No, probably because of the return issue. Will thieves be able to scan what is in our cars, homes, etc to know what is there to steal. See it's not just about "the stores". How would the ladies like it if someone at the store could tell what size and brand of underwear they are wearing while shopping, etc.? How would you like your car scanned for its contents? Will police not need warrents to scan our possesions?
Privacy has suffered a great deal in our "free society"; how much more will freedom loving Americans be willing to sacrifice? And why?
Posted by: Scott Stanfield | Friday, 03 February 2006 at 01:01 PM
The distinction needs to be made between the use of an RFID zapper to protect one's own privacy, vs. the use of it to disrupt or harm someone else (e.g. a company's inventory system). In that respect these zappers are like firearms: legitimate for self-defense, not for attacking others.
I see no reason why a company couldn't manufacture an RFID zapper specifically for personal privacy protection, and constructed in such a manner as to discourage illegitimate uses. For that matter, retailers could install zappers at a location just beyond their checkout areas, to enable their customers to zap the RFID tags on merchandise they just purchased.
The use of RFID as a "peeping-Tom modality" necessarily leads to righteous resistance that is well-grounded in our own traditions. Above-board personal and commercial RFID "privacy protection devices" would fulfill a legitimate need and at the same time reduce demand for "underground" solutions that might otherwise mutate into aggressive weapons.
BTW, I mightily object to RFID peeping-Tomism, and I destroy such RFID tags as I find in my consumer purchases when I get them home. As for chips implanted in the human body, they can put a chip in me when they have my cold dead corpse.

Would it work to put a US passport in a microwave and kill the RFID chip that way ?
Posted by: Sarkast | Friday, 17 March 2006 at 03:43 PM
RFID chips are used for inventory tracking and more importantly they are now used to track animals. If a sample of meat is tested and is positive with mad cow and someone has disabled the tracking device then the proper action cannot be taken against the source of infection. SInce only a tiny fraction is ever tested (as the testing of all meat would be prohibitively expensive)the source of contamination will exist until another sample from that source is tested. That means many people will get infected with an incurable disease. You really need to think before you act.
Posted by: Kirk | Saturday, 29 July 2006 at 11:12 PM
Kirk, you are confusing several different things. Implanted RFID tags are part of NAIS, which isn't going to go into effect till 2007/8 in the US. Tracking of animals won't cure or prevent BSE/Scrapie/E.Coli because it isn't intended to. It is intended only to *appear* to be Doing Something™ to the countries we export agricultural products to.
There are a number of reasons that NAIS is broken, defective and can never fulfil its publically stated mission. Starting with Revelations 13:16-17 - He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead, so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name.
Currently the tagging and registration is voluntary. Did you know that to "register" your farm that you have to give up your 4th Amendment right to search warrants? That every time an animal leaves, enters, is born or dies on your registered facility that you have to file electronically with NAIS? Or that NAIS is privatizing the database before it is even live?
ISO 11785 compliant implants start at $1.50 and go up. Only small farms have to use them. Large "farms" that keep critters in lots from birth to abattoir only have to serialize the lot, not the animals, so places that raise thousands of animals won't be paying $1.50/animal.
Sample Use Case:
- You raise cattle for the beef industry. Each calf when born requires tagging and notification for the USDA.
- You raise large amounts of cattle for the beef industry. Each calf requires registration, but no tagging as long as they stay in the same lots.
- You want to ride your horse to visit your family down the road. You must notify USDA when the horse leaves the registered "source" and when it arrives at the destination. You'll have to notify the USDA when it returns home. A filing fee must be paid for each leg of the journey.
- You take your horse out on the trail where it might comingle with other horses. You guessed it: notify and pay.
- Your kids raise sheep for 4H. They've already been tagged and registered. When you take them to the show/fair, you have to notify the USDA and pay the fees when you leave the farm and come back from the show.
- You raise sheep. They never leave your farm. You want to hire a stud to come visit to knock up your ewes. Now all your sheep must get RFID tagged.
- You raise quail and partridges for a local hunting club. You're out of business by 2009.
- You raise fish. Good luck tagging them with compliant rfid tags. You're out of business by 2009.
- You are Amish. Your religious beliefs prohibit you from obeying this law. Welcome to the tribulation.
- You've been farming since before time began. Now you must purchase a computer and internet service to comply with registration and reporting requirements. The USDA does not plan to begin notifying farmers that they are covered by the NAIS requirements until mid 2007, long after the comment period expires, and about 6 months before it becomes mandatory.
The claimed reason for creating NAIS is to cut down on E Coli, BSE and "animal bioterrorism." To eliminate E Coli infection of beef, all the industry would have to do is have the cattle graze on grass for the last 5 days before slaughter. Instead, many cattle stand knee deep in their own urine and feces in feed lots. The US forbids 100% testing of cattle for BSE (Europe and Japan require 100% testing), and permits it only for visibly symptomatic animals. Since it takes 4-5 years for the symptoms to become visible in infected cattle, and most beef cattle are slaughtered before they reach 4 years old, the failure to be able to mitigate BSE in US beef supplies is obvious. There haven't been any incidents of "animal bioterrorism" that I've ever heard of. Foot and Mouth disease was eradicated in the US over 70 years ago.
None of the regulations can meet the stated requirements. This means that the regulations exist for some different reason than the stated ones. The general consensus in the farming community is that these regulations are being made to make the general public less fearful when contaminated meat comes from a packing plant. We must protect the profit margins of big-farming no matter how much it screws the public or the smaller farmer.

With the additional of how this could be accomplished.
A small thermo-nuclear detonation in a close proximity of the RFIDs would accomplish the desired disabling.
