Introduction to Biometric Technologies and Applications

RF Field Fingerprint Sensors • A low radio frequency (RF) signal is injected into the finger, then read by the sensor array on silicon which act like receiver antennas. • The signal strength at each antenna (or pixel) depends on the distance between the skin at that point and the sensor. This is how the image of the fingerprint is produced.
