How small can you go?

When it comes to RFID tags, smaller may not always be better but it is generally more adaptable when it comes to implementation options. Hitachi may have hit the ultimate in RFID packaging flexibility when they displayed a chip measuring 0.05mm x  0.05mm (think of a dust speck). The new chips, if in production, would allow for RFID tags to be embedded in items as thin as a piece of paper. There's a downside, in the 4mm antenna that's currently required, but Hitachi engineers say they're working on that, too.
