Electromagnetic emissions and performance for proximity RFID

We examined the electromagnetic emissions, and performance of commercial High-Frequency (HF) proximity Radio Frequency Identification (RFID) systems including their susceptibility to jamming and eavesdropping. These proximity RFID systems are used in an increasing number of financial, identification, and access control applications. We performed investigations of whether transactions can be detected and read at a distance. The measurements were performed to determine the power radiated by commercial systems and how they perform in adverse electromagnetic (EM) environments.
