7.5 Micron Thick RFID Tag

Posted by ScuttleMonkey on from the next-comes-the-RFID-kick-me-sign dept.

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."

  1. The smaller they are, the harder they fall by Jordan+Catalano · · Score: 4, Insightful

    Shouldn't a smaller chip mean that even less radiative power is needed to overload and inactivate the tag? So... good news?

  2. ... but you still need an antenna by helix_r · · Score: 3, Insightful


    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.
