7.5 Micron Thick RFID Tag 149

YesSir writes "The EETimes is reporting that Hitachi has a breakthrough in RFID technology that they are planning to show at this years ISSCC (International Solid-State Circuits Conference). The new RFID chip is their newest mu-chip that, measuring in at 7.5 microns, is ten or more times thinner than a sheet of paper and comes complete with 128-bit identifying goodness."

      There might be some problems with putting it in paper:

      1. Module has to stay in the paper. This is harder than it sounds.
      2. Antenna (for contactless) has to be much thinner and more flexible than paper. Many transit systems using microcontrollers embedded inside tickets might already have this, but the paper is pretty thick.
      3. Antenna has to stay in the paper.
      4. Paper tracking can be done already with UV inks. I'm not sure which would be cheaper though.

      Does anyone know what kind of microcontroller is used on the transit system tickets?

    This seems to me that artists could embed an RFID chip in their art, such as under paint, or even in a tatoo, to identify their work. Such a thin tag could be under the label layer in a CD/DVD/etc to identify the origin, to identify whether the work is original and/or authorized. But, of course, someone will eventually find a way around this as they did with CSS and other encryption.

            Easy. Carry a battery-powered baby monitor that uses the 900MHz band in your pocket. Those things are wonderfully capable of farking up any and all passive RFID tag reads. Just about anything that uses the 900MHz band will do. The reflective signal of a passive tag is extremely weak, and any powered emissions source at close proximity will mask an RFID tag's signal. Chances are that since there's no error correction in Gen 1 and Gen 2 tag constructs, the signals from any baby monitor will cause numerous phantom reads as well.

            Look at the biggest challenges in passive RFID today, and it'll show you exactly where the vulnerabilities are. Proxomity to metal, proximity to liquids, proximity to other tags, false reads frequency, sensitivity to interference and tag failure rates provide all sorts of opportunities for general mayhem. It don't take much.

    ten or more times thinner

    That little bit of ineptitude is nowhere in the article; so the blame passes to the submitter.

    "10 times thinner / (less in any form or fashion)" is exactly like saying "300% less". It is an ridiculous statement made by a math illiterate. It is, by definition, impossible for anything to lose more than 100% of it's value.

    People see the statement "3 times larger" and, because they can barely add 2+2 without an electronic calculator, they think "3 times smaller" is a valid statement.

    [/rant]
    • I'm sorry, but I don't understand what's wrong with saying something is 10 times thinner than a sheet of paper.

      In math-think I'd write 1x = (1/10)y where x = sheet of chip and y = sheet of paper.

      right????

      • The reason you don't understand what's wrong with saying something is ten times thinner is that you believe that you can apply the rules of math to formulate proper English. Natural languages are not nearly as amenable to logical analysis as is the realm of math.
    • What something means mathematically is entirely different from what something means literally. Besides if you just interpret "times smaller" to mean 1/ then it makes perfect sense to both parties.

    • >ten times thinner

      Another way to look at it is that the scale is missing. To say that something is "ten times thinner" you have to know what unit of thinness is being used. Same with "ten times quicker" or "ten times slower", as you say. It's backwards construction.

      Marketers love to use this mangling, because it sounds better to the untrained ear than "one tenth as [thick, far, fast]". More is always better, so ten times something is better than one tenth of something.

    I remember seeing an ad a few years back about how you would be able to push your loaded cart through the check-out and all the groceries would be scanned and totaled and you could just pay and go without the need unload the cart and wait for the checker to scan and reload everything. The closest I've seen is the "self checkouts" at the grocery stores (anyone else have these?) where you scan and bag the items yourself. (I'm still wondering how they would handle items that are sold by weight)

    Like any technology this could have its uses (as the above example) and I really think a lot of the concerns are exaggerated (I have a hard time getting my RFID badge to trigger the door locks here, even when it's practically touching the reader). The tinfoil hat crowd and their "the black helicopters will read these as they fly over your house" don't make a lot of sense to me. But maybe the joy of the thing is in conspiracy, not the logic? My read on this is that in order to generate enough power to be read at any great distance (like from outside your house) you'd have to paint the tags with enough radio to fry the occupants.

    Anyway, so far it's all talk and nothing much else of practical value. Maybe the packaging of the next Duke Nukem will have RFID? :o)

      At the self checkouts in my neck of the woods, you put the item on the scanner/scale to measure the weight, then use the touch screen to navigate to the item that it is. You could also print a barcode label at the self-serve barcode printer in the produce dept.

      Not sure how closely they watch to make sure you're paying for the right item, though.

    What I really want out of RFID tags is the ability to scan 1000s per minute. I've got a large room, a library of documents.

    Yes, of course, its not surprising that the RFID chip itself can be incredibly small. What most commentators are missing is that YOU STILL NEED AN ANTENNA to access the thing.

    A "long-range" (> few inches) RFID tag needs a relatively large area antenna, like the size of a business card.

    A "near-field" tag can have an antenna that is a few millimeters wide, but then your reader has to be very close-- almost touching.
