    Man, who would have known that the new RFID tags would stir up such a huge
    storm. They will become mandatory for all Wal Mart (and most other stores)
    suppliers to have on all of their items sold.
    Heres a sample one of many:

    Any ideas for schematics that will kill off these id tags once the item gets

    Slightly off-topic, but for the last month I've been setting off the door
    alarms at the local Wal-Mart while passing through them, and have been
    seareched several times.. Nobody could figure out why, until a elderly
    passer-by said, "are those steel soled shoes...thats whats doing it!". The
    store security guy and I tossed one of my shoes through the door sensors,
    and it promptly set off the alarm. Seems like my size 13 steeled soles are a
    perfect match to the antishoplifting tags....just much harder to hide.

    most of the RFID tags are passive,

    meaning that they are not active

    so deactivation as you stated is not even an option.

    actually the retailers do not want to pay the money for the machines
    that deactivate the RFID

    bills blow up when hit them with the nuke

    A Critique of Proposed Industry Solutions

    The RFID industry has suggested a variety of solutions to address the
    dangers posed by RFID tagging of consumer products. Among them are
    killing the tags at point of sale, the use of "blocker tags," and the
    "closed system." We examine each strategy in turn.


    Some have proposed that the RFID tag problem could be solved by killing
    the tags at the point of sale, rendering them inoperable. There are
    several reasons why we do not believe this approach alone and without
    other protections will adequately protect consumer privacy:

    Killing tags after purchase does not address in-store tracking of

    To date, nearly all consumer privacy invasion associated with RFID
    tagging of consumer products has occurred within the retail
    environment, long before consumers reached the checkout counter where
    chips could be killed. Examples include:

    Close-up photographs were taken of consumers as they picked up
    RFID-tagged packages of Gillette razor products from store shelves
    equipped with Auto-ID Center "smart shelf" technology.

    A video camera trained on a Wal-Mart cosmetics shelf in Oklahoma
    enabled distant Procter and Gamble executives to observe unknowing
    customers as they interacted with RFID-tagged lipsticks.

    Plans are underway to tag books and magazines with RFID devices to
    allow detailed in-store observation of people browsing reading
    materials. This potential was demonstrated recently at the Tokyo
    International Book Fair 2003. According to Japan's Nikkei Electronic
    News, "By placing tag readers on the shelves of bookstores, the new
    system allows booksellers to gain information such as the range of
    books a shopper has browsed, how many times a particular title was
    picked up and even the length of time spent flipping through each

    We recognize the need for stores to control shoplifting and make
    general assessments to enhance operations. However, monitoring and
    recording the detailed behaviors of consumers without their consent,
    even if only within the store, violates Principles of Fair Information

    Tags can appear to be "killed" when they are really "asleep" and can be

    Some RFID tags have a "dormant" or "sleep" state that could be set,
    making it appear to the average consumer that the tag had been killed.
    It would be possible for retailers and others to claim to have killed a
    tag when in reality they had simply rendered it dormant. It would be
    possible to later reactivate and read such a "dormant" tag.

    The tag killing option could be easily halted by government directive.

    It would take very little for a security threat or a change in
    governmental policies to remove the kill-tag option. If RFID tags are
    allowed to become ubiquitous in consumer products, removing the kill
    option could enable the instant creation of a surveillance society.

    Retailers might offer incentives or disincentives to consumers to
    encourage them to leave tags active.

    Consumers wishing to kill tags could be required to perform additional
    steps or undergo burdensome procedures, such as waiting in line for a
    "killer kiosk" and then being required to kill the tags themselves.
    Consumers who choose to kill the tags might not enjoy the same
    discounts or benefits as other consumers, or might not be allowed the
    same return policies. In many areas of privacy law, this retailer
    incentive is recognized, and there are legislative prohibitions against
    inducing the consumer to waive their privacy rights.

    The creation of two classes of consumers.

    If killing tags requires conscious effort on the part of consumers,
    many will fail to do so out of fear, ignorance, or lack of time. Many
    will choose not to kill the tags if doing so is inconvenient. (The
    current "killer kiosk" requires loading one item at a time, a lengthy
    and time consuming process.) This would create two classes of
    consumers: those who "care enough" to kill the RFID tags in their
    products and those who don't. Being a member of either class could have
    negative ramifications.


    RFID blocker tags are electronic devices that should theoretically
    disrupt the transmission of all or select information contained on RFID
    tags. The proposed blocker tag might be embedded in a shopping bag,
    purse, or watch that is carried or worn near tags with information
    consumers want blocked.

    Blocker tags are still theoretical.

    According to our understanding, the blocker tag does not yet exist.
    Until a blocker tag is built and tested, there is no way to know how
    effective it will be and whether it can be technically defeated.

    Encourages the widespread deployment of RFID tags.

    The blocker tag might encourage the proliferation of RFID devices by
    giving consumers a false sense of security. While the proposed
    invention is an ingenious idea, it's one that could be banned or be
    underutilized if consumers become complacent. It's also possible that
    such an electronic device could be technically defeated either
    purposefully or because it stops functioning naturally.

    The blocker tag could be banned by government directive or store

    Consumers could lose the right to use blocker tag devices if the
    government deems that knowing what people are wearing or carrying is
    necessary for national security. They might disallow the devices
    altogether or name selective spaces in which blocker tags would be
    disallowed. It is not inconceivable to imagine a ban on such devices in
    airports or public buildings, for example.

    RFID is the most epic new second coming out of the "closet" today.
    Thanks to people like Katherine Albrect founder of CASPIAN, more and
    more consumers are becoming aware of the RFID movement and how it will
    effect the consumers privacy rights and where the RFID will lead us
    tomorrow. Katherine has a strong following from the web perspectives
    other medias. We see leader's stepping up to the plate and expanding
    the words of Katherine. Already there are hundreds of blogs and web
    pages listing their concerns of what will become of the RFID. However
    there are the Industry gazettes, journals and blogs where they spin
    RFID as the best thing since apple pie.

    RFID - The Perfect Storm

    ZombieWire RFID world News - Everything you need to know about RFID and

    (PRWEB) December 3, 2004 -- We the consumers are at a brink in life
    where we will move from the simple task at the market place to purchase
    supplies for home, office, motor home and others as you can imagine. We
    walk in the store and purchase these items and hand down cash or card
    for the items scanned using the barcode system. Seems pretty simple
    however none threatening to your privacy. However these times have come
    to an end. You might as well say it is at your door right now, but 90
    percent of all consumers are non- aware of this fact. This reason is
    that if that percentage knew of this fact then the process would stop
    in its tracks because of what is behind the new movement and normal
    people would not want it to continue with this.

    Wal-Mart the "super power" monster store found a new direction in
    how they will run their shop and being so they informed the supply
    chain around the world to make it so with all products purchased by
    Wal-Mart. Having mandated the supply chained complied and this set off
    the shot heard around the business world. All retail competitors had to
    follow the lead in order to compete. The mandate is that all items sold
    via Wal-Mart will have a Radio Frequency Identification chip or in
    simple terms RFID chip implanted in all products sold.What is an RFID?

    What is RFID?Radio frequency identification, or RFID, is a generic term
    for technologies that use radio waves to automatically identify
    individual items. There are several methods of identifying objects
    using RFID, but the most common is to store a serial number that
    identifies a product, on a microchip that is attached to an antenna
    (called an RFID transponder or an RFID tag).

    AT this time as the Trojan horse at the door consequently there is
    nothing we can do about it because the gears are in motion; however, we
    need to learn everything we can about the RFID movement to maintain our
    privacy rights. You will not be able to "sell" any products without
    the RFID as you see in the barcode today. This RFID chip will go home
    with you and one day your home will be filled up with RFID chips. How
    would you feel if your home items were public knowledge from a certain
    book you have to what style and size under pants? You ask how that may
    become public awareness. Theoretically speaking if a van pulled out
    side your home with a RFID transponder, there is way for that person in
    the van to inventory your private life, and who knows what would take
    place once that knowledge is out. You ever heard the saying "keep and
    honest man honest: approach? Think about this!

    Likewise, the RFID market has not stopped here and it will continue to
    transpire to greater levels beyond our comprehension. There is a RFID
    chip out now called the Verichip. This Verichip is imbedded in the
    human body. This Verichip may store your Visa Card, bank debit card and
    social security and other information that takes the place of your

    The perfect storm: In theory, what will become of the Verichip by means
    of how we see progress continue to unfold? Will the Verichip be mandate
    as the RFID chip is mandate for all products you buy or sell?

    I will leave you with this "Buyer Beware"

    Can't you just open your cell phone and paint over the gps antenna with
    aluminium paint? My hand held GPS fails utterly when placed into
    aluminium foil.

    My cell phone is old enough not to have GPS installed and I'm not
    replacing it until I'm forced to.

    You need to study up on how cell phones work. They know which "cell"
    you are in *without* using the GPS.

    I personally do not own or use cellphones. It is for those who have to be
    always reachable, like a plumber or a webmaster. I do not think I belong
    into this category.
