Reported in the register yesterday, Hitachi have developed the world’s smallest RFID chip on the market. These chips, pictured right, are smaller than the thickness of a human hair at 0.04mm x 0.04mm and with a working name of “Powder”.

Maybe now we can have a fridge that can sense it’s contents and perhaps even place an order with the local supermarket for more milk. It’s even conceivable that the fridge could “learn” your buying habits and perhaps offer different purchases. Unbelievable? RFID was supposed to be a replacement for the barcode, originally, and really only due to the relatively high cost for RFID implementation have we not seen them attached to everything in the supermarkets. So when these inevitably wind up attached to everything for the sake of the supermarkets, you can be sure that off the back of that new innovations for their use will be found. [SHOW ME]
