Specter transforms the Flipper Zero into a sophisticated counter-surveillance tool designed for detecting active 13.56 MHz NFC readers. This tool passively listens for RF emissions from hidden skimmers or covert readers, providing real-time feedback on the presence and type of detected devices, as well as the cleanliness of the environment. Notable features include an analog EMF gauge for proximity detection, a fingerprinting capability to classify the type of NFC reader, and the ability to log and monitor over time, enhancing situational awareness for security professionals.
