The combination antenna and rectifier can pick up residual radio waves from your phone to power itself. This new technology could apparently drop the cost of installing NFC to as little as one penny per unit, while offering up additional two-way functionality over its RFID rival. And if there's a speed boost in the process, well, all the better.
