Abstract. In this paper, we study the applicability of an emerging RFID-based communication technology, NFC (Near Field Communication), to ultra-low power wireless sensors. We present potential application examples of passive and semi-passive NFC-enabled sensors. We compare their NFC-based implementations to corresponding implementations based on short-range radios such as Bluetooth and Wibree. The comparison addresses both technical properties and usability. We also introduce Smart NFC Interface, which is our general-purpose prototype platform for rapid prototyping of NFC and Bluetooth implementations. Two pilot sensor implementations and an NFC-Bluetooth gateway implementation based on our platform are presented and evaluated. Finally, needs and possibilities for technical improvements of available NFC technology are discussed.

In this publication several Near Field Communication (NFC) based sensor demonstrations and related measurements are discussed. These include basic temperature sensor applications and some more complex scenarios with external sensors and actuators. The reader device can be a commercial NFC enabled mobile phone or specially developed hardware. Based on the experience gathered with demonstrations and prototypes, the main features of an optimal NFC circuitry for low cost batteryless NFC enabled sensor devices are specified. Index Terms-batteryless, NFC peer-to-peer, Smart NFC Interface, ultra-low power, wireless sensors.
