N2 - Tag antenna damage is a common phenomenon in real-world RFID systems, which incurs severe changes of antenna impedance and antenna gain. Existing RFID sensing systems leveraging signal features (e.g., phase readings) related to antenna impedance or gain are vulnerable to such tag antenna damage jeopardizing sensing accuracy and reliability. In this poster, we introduce RFANT-Checker, the first automatic system that provides accurate and fast detection of tags with damaged antenna. Impedance-induced phase shift and gain-induced minimum transmission power coefficient are jointly exploited as fingerprints for selection and validation. We implement RFANT-Checker with COTS devices and evaluate it on 84 examples of commodity tag. Experiment results demonstrate the high detection accuracy of up to 97% and low time overhead of at most 10s.
