University Research Tracks Everyday Activities via RFID

A team of researchers from the University of Michigan and the University of Washington have completed the first round of testing for an RFID-based system that uses UHF RFID signals to identify a specific tag, and that uses fluctuations in these signals to understand changes in the field around that tag. The result could be a solution with which users could understand whether a tagged item has been moved or been interacted with, as well as if someone has approached or left the tag's vicinity.
