Abstract.
Want to detect the presence of RFID readers? Want to control when a RFID tag is active or readable? We describe how to do both using bits of copper and card, and some readily available electronics hardware. RFID tags are found everywhere, and RFID readers are used to track nearby tags for purposes such as asset tracking, electronic payment, and mass transit systems. For those who want to experiment with RFID, the technology is almost always black boxed, making it difficult to have much control over its workings. We offer two simple, inexpensive exercises – building a RFID reader detector and a tilt-sensitive RFID tag – that reveal some of the inner workings of RFID and show how the technology can be extended to support interesting new interactions.
