The PROXGRIND RF Field Detector is a compact diagnostic tool used to identify and measure the presence of radio frequency fields generated by proximity card readers and other RF-based access control systems. Security researchers and access control technicians often use RF detectors to quickly determine the operating frequency of an RFID or proximity reader before performing compatibility testing or hardware evaluation. The device detects RF emissions and provides a visual or audible indication of signal presence. This makes it a useful tool during access control system surveys, reader installations, and authorised security assessments involving RFID infrastructure.
