|Title:||Identifying RF Identification Cards from Measurements of Resonance and Carrier Harmonics|
|Published:||May 27, 2010|
|Abstract:||We show that careful measurements of the unloaded resonant frequency and quality factor of radio frequency identification proximity cards allow identification of different card models and, for the set of cards we studied, identification with minimal error of individual cards of the same model. Furthermore, we show that card identification performance is improved by considering an electromagnetic signature that combines measurements of the energy at carrier harmonics during a reader-card transaction together with unloaded resonant frequency and quality factor measurements.|
