Countering Big Brother or Disrupting Society?
Published on January 9, 2006 By singrdave In Gadgets & Electronics
Can you say, "Accessory Before the Fact"? Knew you could.

In the latest attempt to undermine our commerce system, people have discovered a way to disable RFID chips. RFID chips are small wire coils embedded into everything from passports to consumer products to Mobil Speedpass cards. It allows a consumer to conveniently swipe their RFID chip in front of a panel and debit one's account, identify the user, identify the product, etc.

RFID chips are also the subject of conspiracy theorists and Big Brother watchers as the new Mark of the Beast. In the eyes of these nutjobs, RFID would allow the government to track you from space, read all your credit card purchases, and basically spy on you from the time you left your house to the time you came home at night. (At which point, your house's internal microphones would switch on, apparently...)

Well, engineers have created a small EM pulse device that will permanently disable these RFID chips and allow us to "not be tracked by Big Brother". It copies the microwave-oven-method, but in a much smaller scale. It generates a strong EM field with a coil, which should be placed as near to the target RFID tag as possible. The RFID tag then will receive a strong shock of energy comparable with an EMP and some part of it will blow, most likely the capacitor, thus deactivating the chip forever. From the manufacturer's website:

The TagZapper is being developed to be a light weight, handheld, device for deactivating RFID transmitting devices.
This is intended to fulfill consumer demand for a means to protect their privacy.




Proposed scenario:
A consumer purchases a six-pack of beer at a convenience store.
After exiting the store the consumer uses her TagZapper to disable the RFID tags.
At this point the consumer is able to transport and consume her purchase without being monitored by any commercial or government agency.


Once again, can you say "Accessory Before the Fact"? If a business is using RFID technology to counter shoplifting, I can walk into the store, zap the RFID chip inside that six-pack, and walk out of the store without tripping the alarms. If caught shoplifting, I could then turn around and sue the RFID Zapper company for giving me the equipment that enabled me to steal. That's a liability that the company is going to have to deal with if they're going to put a product like this on the market.

Better yet, what about RFID chips used to track medical conditions? I could zap somebody's medical history.

Of course, conspiracy theorists are going to cry that RFID technology can be used to track individuals. And that this product is a counter to the growing ease at which the US police state watches every move we make.

Obviously RFID manufacturers will need to figure out how to defeat something like this. Similarly any chip on board a satellite needs to be "hardened", be able to take the abuse of space such as radiation and extreme temperatures. How soon will we have hardened RFID tags? RFID has been around for ten years; have we really been that exposed for that long?

What gets me is that people actually think the government is spying on Americans through RFID chips. There are so many more reliable ways to spy on Americans...

There has been RFID zappers for a very long time.  They are called Magnets.  Works on Hard drives, and floppies as well!

Spychips.com details how to kill an RFID chip:

Q: What do I do if I find an RFID chip? Can I kill or disable it?
A:
You can disable a chip for all practical purposes by disconnecting it from its antenna. It is usually pretty obvious where the chip is located in an RFID tag (all the antennas will run to it). Once you find the tiny black square you can use a pair of scissors or a knife to cut it off. To ensure that the tiny chip cannot later be read (assuming anyone could even find a device so small), you can puncture it with a straight pin, crush it, or pulverize it. (Note: While burning or microwaving can destroy a chip, we do not recommend these methods because of fire risk. See the Q & A below.) Do not try to "drown" it, since water does not generally destroy RFID chips. Running a magnet over the chip will not work, either.


So I guess a magnet won't do the trick. Apparently you need one of those EM pulse gadgets.

is a good source of imformation.

RFID is too easily circumvented and disabled to be a viable technology.
Someone who really wants to disrupt or steal or play can have a day with it, especially with how ubiquitous it is becoming.

"Of course, conspiracy theorists are going to cry that RFID technology can be used to track individuals"

Obviously, you never heard of MIL-STD 3G RFID

I'm not worried about TagZapper, it's easily defeated.
RFID is a generational technology, while the commercial RFID is in the second generation, While Military RFID are well into the fourth generation (IRFID)spearheaded by DARPA. See Microsystems for spectral exploitation and sensor dominance
RFID techology will only last until Nanotechnology matures to replace it.

It's not the technology of RFID that bothers me, or even the fact it exists. I even think it's a good idea for tracking products from manufacture to point of sale.

In fact, not much of RFID bothered me, until...

Until the complete supitidity of "Broadband over Powerlines" was approved.

The low power output of RFID tags makes them both great for product tracking and awful for any kind of surveilance. However, with BPL, anything you plug into your power sockets will be "online".

What you have in your home will be open to government, thieves, advertisers, and whoever else decides to take a peek. Why bother with gun registration laws if all your guns have RFID tags in them?

I wrote an article about RFID awhile ago, and looking back, I admit I came off as a paranoid conspiracy theorist. Bakerstreet (rightfully) pointed out that it's not the technology that is the problem, but certain applications.

Yes, there will be "RFID Zappers", and the makers of those and the makers of RFID tags will keep busy trying to stay one step ahead of each other (just like spyware and spyware detectors/cleaners now).

However, spyware is a great example of showing that there are people out there that are interested in invading our privacy for their own purposes, so being aware and even fighting against it isn't all the wacko...

But I'll admit, it's easy to cross the line. ;~D

RFID is a dangerous technology deserving to be countered.

Deference:
RFID is a dangerous technology deserving to be countered.

So, Def... is it insidious? Does it give away too many bits of personal information? What is your hangup about it? Was it dangerous before it was counterable? I'd like to hear your opinions on the viability of RFID technology in general.

I won't leave you hangin' too long, Singrdave, I'm working on a decent response as opposed to simply giving you rhetoric without links, maybe this will be a new article, I've been working on several and have been really too busy to be on JU lately other then to leave 'post and run' messages..

Thanks for your open-minded inquiry...it deserves a good answer...
