About the size of a grain of sand, this RFID (Radio Frequency Identification) chip is the smallest of its kind in the world.
The basis of this type of technology is that a scanner can be used to identify unique information on each chip. Packed into each of these tiny devices is a unique 128-bit code or 26 character unique identification number, which is implanted during manufacturing. Like a fingerprint, each chip is unique. Because the chips are so small they can be embedded in all sorts of new applications — such as paper or coatings — for purposes of identification and validation. This short video from IBM paints a picture of what grocery stores will be like with RFID chips on every product.
The chip itself has no power source, instead deriving the power it needs from the radio waves it receives when being read by the scanner. The chip uses special ROM memory, so it prevents counterfeiting, copying and tampering. Other RFID chips have been developed for tracking products in an open supply chain or for the identification of lost pets; this chip’s qualities suit it especially well for item validation. Microsoft is taking RFID to a new level with their Sixth Sense project designed to bring RFID to your office systems. Your calendar will know where you are!
