Lessons Learned from RFID Field Test

muddy_mudskipper writes "From John Young's cryptome.org website, is a newly posted pdf copy of the "Lessons Learned from RFID Field Test" as compiled by the Field Test Program Manager of the Auto ID Center. It is interesting to note the photographs of the different passive RFID antennas that could be used in product packaging - some small enough to fit into a soap box. Also curious is how many sector antennas have to pepper the test center in order to approach 100% RFID readability. 'In March 2001 a team comprised of Auto-ID Center sponsors (technology & end users) was assembled to plan and implement a Field Test aimed at taking the Auto-ID EPC technology from the laboratory to the real world environment with the objective of proving the power and effectiveness of the EPC and to blaze a trail for future adoption' "

    One thing to look out for is the resonant frequency. We were trying to use RFID tags inside professional tape decks, to tell which tape was currently in the decl - it was an asset management project.

    the only useful (in terms of range) RFID tags at the time (18 months ago now) were resonant at 13.5 MHz, which is very very close to the colour burst frequency of PAL TV... not ideal for the inside of a Pro. tape deck :-)

    Complete redesign, readers outside and having to motion sensors to detect the tape's direction (if it was going in or out) delayed us quite considerably :-) Always read the small print....

      You're probably not going to get away cheaply, I work with RFID tags on a regular basis. You know those identity cards everyone carries at work now, most of them are RFID cards (tags). An easy way to tell is, if you swipe the card near a small box that goes beep to go through doors, that is an RFID tag you are swiping. The technology is cheap enough, if you don't care about range. But if you want to get beyond about a foot, you're looking at some real money. Though that is on the reader side, the cards themselves are not overly expensive, and there are tags specifiaclly made for inventory tracking, which can be stuck on to just about anything (1 inch adhesive disk).
      Now, putting it on a metal tool, well that's going to screw your range, and be damn sure that its not close to a power supply, or forget it. If I put a reader next to one of the 12v power supplies we use here, I have to smack the reader with the card to get it to read, and even then it doesn't always recognize the card. Put the reader on a metal surface and its only slightly better. You have to remember, your working with radio waves, they tend to be affected by things like metal and EM fields. Also, if the tags are too close to each other, they tend not to read.
      Try this sometime, if you get a chance: Borrow a few of the ID badges from your co-workers, stack them together and present them to a reader, the reader will fail to read any of them.
      In all, I don't think you'd be happy with RFID tags for tracking your tools. The range would suck, it would be a bit costly, and the system would probably be flaky due to all the metal involved.

    YOU MUST BUY NEUTRALIZED OR FOREIGN TIRES!!!!! Soon such tires will become illegal to import or manufacture.

    Using these chips to track people while they drive is actually the idea of the us gov, and current chips CANNOT BE DISABLED or removed. They hope ALL tires will have these chips in 4 years and hope people have a very hard time finding non-chipped tires. Removing the chips is near impossible without destroying the tire as the chips were designed with that DARPA design goal.

    They are hardened against removal or heat damage or easy eye detection and can be almost ANYWHERE in the new "big brother" tires. In fact in current models they are integrated early and deep into the substrate of the tire as per US FBI request.

    Our freedom of travel are going away in 2003, because now there is an international STANDARD for all tire transponder RFID chips and in 2004 nearly ALL USA cars will have them. Refer to AIAG B-11 ADC, (B-11 is coincidentally Post Sept 11 fastrack initiative by US Gov to speed up tire chip standardization to one read-back standard for highway usage).

    The AIAG is "The Automotive Industry Action Group"

    The non proprietary (non-sokymat controlled) standard is the AIAG B-11 standard is the "Tire Label and Radio Frequency Identification" standard

    "ADC" stands for "Automatic Data Collection"

    The "AIDCW" is the US gov manipulated "Automatic Identification Data Collection Work Group"

    The standard was started and finished rapidly in less than a year as a direct consequence of the Sep 11 attacks by Saudi nationals.

Another reason to leave "finger print on Driver license" California, but Ohio gets it next, as will every other state eventually.

    The AIAG is claiming the chips reduce car theft, assist in tracking defects, and assists error-proofing the tire assembly process. But the real secret is that these 5 cent devices are a us government backed initiative to track citizens travel without their consent or ability to disable the transponders in any way.

    4. There are no real advantages to consumers for each and every item to be remarked with an RFID tag vs a barcode that is already on the item.

    But, to giants like Walmart, RFID tags are just ANOTHER way of tracking products. Barcodes are already used at all Walmart distribution centers to mark pallets and crates or boxes.

    Lastly, if you read the industry notes, you'll learn that RFID tags are becoming smart tags, and they will begin to be much more than mere number transmitters. In the future, RFID tags will be computers with storage ability and that will make you a walking target for stores and companies to monitor as you walk within stores or malls, you will be tracked, and your purchases identified even by other stores who want to see what you purchased at another store.
