RFID paperclip tags

Abstract

In this paper, we present RFID tags which double as paperclips. These tags use standard metal paperclip bodies as antennas. This way, the paper holding function of each paperclip is augmented by its RFID functionality. Paperclip tags can be designed so that as they slide on or off the stack of papers, their antenna wires either touch or separate, changing tag sensitivity and causing tags to be activated or deactivated. We provide a survey of the prior work, describe the concept of a paperclip tag, demonstrate several prototypes accompanied by experimental results and electromagnetic simulations, and discuss possible applications and future work.
