RFID: The New Big Brother ?

Makarand writes "The possibility that we could be tracked not because we have a microchip implant but merely because we wear clothes, eat and carry objects around is real according to this article on C|net news. A technology called RFID (radio frequency identification) consisting of miniscule microchips the size of a single grain of sand that listen to a radio query and respond by transmitting their unique ID can make this possible. Most RFID tags use the power from the initial radio signal to transmit their response and hence can be placed anywhere imaginable. Retailers are adoring this concept and soon everything more expensive than a Snickers bar will sport RFID tags making tracking possible through our own personal possessions. The privacy threat comes when RFID tags remain active once you leave a store and currently the RFID industry seems to be giving 'mixed' signals about whether the tags will be disabled or left enabled by default."

      Yes it will work, its how half of the theft prevention devices work. Look for the square stickers with the coil wrapping around a center square. These are the earlier counterparts to what they are talking about. The gates that check for the tag listen for the response from the tag by emmiting relatively low power signals. To disable the tag, higher power is output, frying the circuitry.

      So to "clean" your, you could emit broad spectrum high power RF noise and nuke the little bastards.

      These anti-theft stickers are not RFIDs. They do not store and respond with IDs. Instead they are simple oscillator circuits which influence the frequency of the detector oscillation. They are not disabled by microwaves but by a magnetic pulse which induces a current high enough to trigger the builtin "fuse".

      This would actually work!

      I used to own a computer store, and we had problems when we had a "flaky" motherboard that would boot but was unreliable, and was still under warranty.

      The distributor would set it up, see it do something, and send it back to us. To fix this, we'd put it into a microwave oven for 3 seconds before shipping it back.

      That'd cook the chips on the motherboard without leaving any visible sign of problems. It would then show no signs of working, and they'd give us a whole new motherboard, and everybody was happy.

      Worked for RAM chips, video cards, sound cards, modems, etc. although we had the most trouble with motherboards.

      There's two types, the magnetic and the RF. Technically the magnetic ones don't have a fuse, but instead are disabled by magnetically saturating the metal. These are the most commonly used tags. The others are actual RF circuits. They don't transmit IDs, true, I shouldn't have given that impression, but the do respond to the broadcast in much the same way the rf tags do.

    I work in the packaging industry and have seen firsthand some of the RFID application processes on folder gluers. First of all, the defect rate hovers around 10%, which makes relying on this technology a dubious proposition.

    I doubt that the practical size is approaching "half a grain of sand," which would make application a nightmare to try to control. And most importantly, RFID tags are like UPC barcodes: they're coded to a single frequency and product, not to each instance of the product! If an RFID tag is enabled on your North Face jacket and you walk in a store, they may be able to tell that you're wearing the jacket, but that doesn't tell them who you are.

    RFID tags need to be printed on paper

    Wrong.

    For one, it depends on the type of device. The ones you see embossed on paper are essentially just antennae that resonate at a certain frequency. There are other versions that are MUCH more sophisticated, though, AND active to boot, and manufacturers ARE anticipating imbedding them in a lot of products permanently (if for no other reason than to save the stores the labor costs of removing them.)

    Do you think the little mylar strips in US money are for COUNTERFEIT protection??? haha. Stack up a few 20's and it wouldn't be hard to spot them at all using the same technology (i.e. finding the resonant frequency of a passive radiator consisting of an array of mylar strips of known size stacked a known distance apart.)

    Before anyone panics there are several things to consider:

    1. Unless the receiver can determine the distance to the RFID tag (and this is usually not the case), the tag's location cannot be determined with any greater accuracy that the distance to the nearest receiver. To "locate" a tag, there must be many expensive receivers no how many cheap tags there are. Remember, we live in three dimensions.

    2. The range of passively powered tags is only a few meters, and they all tend to reply at the same time when a bunch are pinged, causing interference.

    RFID technology has been around for years. Have you purchased a CD or DVD in the last few years? Remember the check-out guy "beeping" it before you left? That's an RFID tag at work. In this instance, it's just a proximity tag that will alert the store if you (ahem) neglect to purchase the product. (The official term for this is "inventory shrinkage.")

    Checkpoint Systems makes RF Electronic Article Surveilance (RF-EAS) tags (the US site is not responding, but the Japanese one is, showing the bulk tags.) And here's a company that sells machines to auto-insert the RF-EAS tag into DVD carriers.

    An amazing amount of effort has gone into reducing the cost of the RFID anti-theft tags. They're typically screen printed, and usually are destroyed when you purchase the product. It's not cost effective to make it re-programmable, as the retailers are playing a statistical game - they're weighing the probability of someone stealing a returned (or defective) unit against the reprogrammable cost that burdens EVERY unit going out the door.

    One step up from this application is the ubiquitous personnel badge that most of us drones are required to wear at the orifice. Here's one from TI (PDF datasheet.) This costs a little more, and is definitley capable of identifying who you are.

    Including, apparently, the poster.

    The microwave oven beam is directional only until it hits the "stirrer", a rotating paddle designed to spread the microwaves all over the interior of the oven (for even heating). Plenty will leak out the front if it isn't shielded.

    The screen does a wonderful job at stopping the (microwave) radiation, since the holes are far smaller than the wavelength -- it "looks" like solid metal to the microwaves.

    As for the energy -- there may be higher total wattage in the microwave beam, but per-photon the higher-frequency light waves have much higher energy. That higher frequency also means the wavelength is small enough to easily pass through the holes in the screen, so you can watch your dinner cooking, or the pretty light show from nuking an AOL CD.
