          This has been discussed. RFID-tags can be designed to withstand such treatment (shielding plus decoupling the antenna in overload situations). Besides, even if it worked it wouldn't save you: RFID tags will be embedded in things which you don't want to fry because you would destroy the useful function as well (_anything_ with electronics, your watch for example).

      My understanding, based on earlier articles that have been posted on this website, is that the RFID tags are specifically built to withstand these sorts of problems.

      They disconnect their antenna if they sense a surge to protect their circuitry.

      And it makes sense -- if you're using these for tracking merchandice, you wouldn't want some shoplifter taking the RFID equivalent to a tazer with them, shorting out the RFIDs, and then walking out with your product.

      What you fail to address is that takes a vehicle and one or two dedicated people per person being tracked. This is the way it should be.

      With RFID we are now faced with situation where a simple globally unique tag is assigned to each RFID tag and can be tracked with simple electronics. A store can track your every movement with a dozen carefully placed receivers by tracking the RFID tag embedded in the soles of your shoes.

      Malls could track walking patterns the same way, and by consolidating and minimg the data, they can probably match up anonymous tracking data with an individual by looking for things like credit card transactions.

      This is not stuff of Sci-Fi or intregue novels, stores want this kind of information and they WILL be using it.

But such a system wouldn't just track suspected Al Qaeda terrorists: it would necessarily track everybody--at least potentially.

      Some are quick to say that the US Constitution guarantees no right to privacy.

      But IMHO, the US Constitution embodies the 1793 State-of-the-Art of distrust of Government and other concentrations of power. That's the whole reason that there are three branches with checks and balances - mistrust of the institution of government. No matter how trustworthy those in power may be today, there's no guarantee that the next batch will be so. Checks and balances were put in place to provide trust - through mistrust.

      Had the Founding Fathers been able to foresee the capabilities of electronic surveillance, they would have codified Privacy into the Bill of Rights. Instead, they did what they could, focusing on late-18th century concerns.

    I'm a triathlete and runner, we've been using RFID to track athletes for years. The main company doing this is Champion Chip. It's a small plastic device that you attach to your shoe or put on an ankle strap.

    The tracking lets them do severl things. First, they get accurate timing and immediate results. They can also track where you've been to make sure that people haven't cut parts off the course. Some people are too creative, a few years back a women hopped on the subway for part of the Boston marathon, but she went "too fast", they got suspicious and reviewed the surveillance cameras in the subway.

    The latest cool thing was in Ironman Hawaii. They had video cameras setup on the course and the chip strapped to your ankle let them know your location all day. Then, you could order a personalized DVD with video of your race. Pretty cool idea, though I didn't personally buy one.

    Technology is not the problem.
    The problem is (as always was and always will be) how people use a technology.
    RFID (or any other technology) is not necessary for a police state as demonstrated by many examples in the past.
    You privacy can be (or most probably: was) violated without RFID too.
    To protect your privacy you need a society that values privacy and have laws that express this. If you do not have that then you are swimming against the flow and your are doomed to failure, no matter if RFID is used or not.
    I would like to point out Europe: there are privacy laws that basically say the following:
    • Personal information can only be collected with your approval (or if mandated by a law)
    • This information can only be gathered for specific purposes (of which you must be informed) and may only stored for a set period of time, which can not be unreasonably long.
    • You can request access to the information about you and request correction or deletion
    • Your info must be kept confidental and correct
    • Your personal information can be given to a third party only if the above requirements are fulfilled

    If you have such laws (and have them enforced) then there is no need to fear RFIDs - but if you don't have them, RFIDs should be the least of your worries.

    The big question, which, it seems to me, gets deliberately fuzzed in all of these discussions, is this:

    Is it acceptable to invade your privacy as long as it is for the purpose of selling you stuff?

    Privacy advocates tend to emphasize the danger that systems put in place for the purpose of selling you stuff might later be used for purposes of political repression. This is a real concern, but a relatively remote one. It's a slippery-slope, speculative, "if this goes on" kind of argument. Yes, I know (mostly from reading Slashdot!) that there have already been instances of such usage creep.

    Let's suppose--implausible, of course, but suppose--that you could somehow guarantee that RFID tags, and all the information that companies gather on you in all sorts of ways, could be freely exchanged by companies for the purposes of selling you stuff, but could be perfectly secured against any other kind of use whatsoever.

    Would that be all right, or not?

    I apologize for, maybe, missing the point but after looking at a few portions of the article, I am beginning to wonder why. For instance:

    RFID isn't a household word today, but within the next few years manufacturers hope to put it into many household products.

    Why would these be needed in 'household products'? I understand they want to track merchandise, but this could be accomplished by putting an RFID sticker on the bottom of the product. That way, you take it home and tear the sticker off when you take it out of the box.

    Perhaps, for clothing, just put an RFID on the main tag. I've worked for a clothing store who used the locking pin security devices found in most stores. They work wonderfully, as you have to destroy the garment to steal it and it only costs a couple of thousand to enough of those things to last a lifetime. I do not see the flaw that needs a new product, not in regards to clothing.

    Both Wal-Mart and the US military have already told their hundred largest suppliers that cartons and pallets must be equipped with unique RFID tags by January 2005.

    This is what I would like to see RFID used for. This will really speed things up at distribution centers, as a forklift coming off a trailer will simple have to drive through the dock doors (assuming the sensor would be there) to put an entry in the company's database saying "this pallet entered the building", meanwhile the operator keys into the computer on his forklift the actual product count.

    For people who will "bite" and say something about computers on forklifts, they have been around for over a decade. I know, I fabricated a prototype mounting platform for a small, wireless computer back in 92. They had blueish LED displays, and were shaped similar to an old RS Model 100 portable, but housed in a sturdy black metal case. I made a nice adapter for Crowne forklifts that allowed the operator to swivel, tilt, and adjust it to his/her most comfortable viewing position. Too bad I didn't know anything about patents back then. They started using this design at all their distribution centers, which equates to thousands of lift trucks. :O

    I do not miss working for Kraft foods. We had weekly 'rallies' where the managers would have a guest speaker. The most memorable one was Penske (wealthy bastard) came to tell us what a great job we were doing, then proceeded to talk about efficiency for the next 45 minutes.

    As far as I recall, the *maximum* distance for passive RFID, under ideal conditions, is 1 meter. Shorter in 'ordinary' conditions. This is one of the reasons passive RFID is not likely to work for 'walk out of the shop' automatic payment, but also why it is also unlikely to be much use for person tracking.

    As a third-party public warehouse, my company is constantly looking at technologies to streamline the process of receiving, storing, and shipping material for our customers. Currently we receive inventory to our docks in two ways: 1. Material is received at the dock and put away in location by warehousemen. They record exactly what came in on a form and turn it in to the office staff who enter the information into the database. This relies on the warehouseman to count the material correctly, fill out the form correctly, then for the office staff to enter the data correctly. The system works, but there are many opportunities for data entry errors. One misread, miscount, mis-type and the data is bad. 2. Material arrives at the dock and barcodes are scanned. The data is uploaded to the system without any human interaction besides the original scan and a later check against the Bill of Lading that came with the load. Much better than the first method, but it comes with its own issues. For one, if the material is put into location, stacked high off the ground, reading barcodes for inventory purposes can be problematic. Also, it relies on a good quality barcode. A lot of our material arrives after long truck/train rides with the material rubbing and jostling against its neighbor resulting in many unreadable barcodes. RFID is the next logical step for us. For the material to cross from the truck/train to our dock and be read by an RFID reader without the warehouseman having to aim a laser at a possibly unreadable barcode would be nice. The customer would also be able to follow that particular RFID all the way from manufacturing through the distribution process. I understand privacy concerns, but in regard to the logistics industry I see RFID as a positive thing.

    every RFID chip has a unique serial number

    I have a question: how long before this system becomes unwieldy. If we're going to track every product sold worldwide, how big will the string have to be? Furthermore, at what point will a database of said string's become unwieldy, and at what point will it become worthless to maintain all that data?

    The retail RFID plans I've seen don't have a unique serial number for every item. They have a unique serial number for every type of item, kind of like a barcode. Granted, that may pose some minor privacy issues of its own. But those problems are minor, and no worse than paying with a credit card.

    More to the point, RFIDs have the potential to save businesses billions -- kind of like barcodes did. And, like with barcodes, those savings will most probably be passed to the consumer.
