Book excerpt: Radio Frequency Identification (RFID) is a technology that uses radio waves to read and capture information stored in a tag attached to an object or location. In this work, we further exploit this technology to find other applications that differ from its classic one and show how powerful RFID can become in the near future. We present three novel ways of taking advantage of RFID technology that go beyond object identification: an RFID-based anti-counterfeiting architecture for electronic components, a passive displacement sensor using RFID technology and an example of how an RFID tag can perform as an actuator, designing a remote control car driven via RFID. In the first of them (Section 3), we showed the feasibility of using this technology in a PCB production line to authenticate a chip during the pick and place stage, by building a demo where a pick and place machine was linked to an RFID reader. Designs of very small RFID tag antennas are proposed but most likely due to variations in the manufacturing process, they didn't perform as expected. In Section 4 we present an implementation of the principle of RFID tag antenna based sensing by developing a displacement sensor. We conclude that displacement can be mapped to antenna bandwidth and best match frequency. However, for a sensor with higher sensitivity for little displacements, we conclude that a reader with higher RSSI resolution is needed. Finally, in Section 5 we propose two different approaches of controlling a car via RFID technology. Approach A uses the RFID IC writable user memory and Approach B the baseband RFID signal at the tag. In the end we conclude that Approach B is much better as far as time response is concerned.
