Home / Do fingerprint scanners contain optical modules
Fingerprint scanners employ three primary modalities: optical, capacitive, and ultrasonic. As the name suggests, this technique relies on capturing an optical image — essentially a photograph. Whether you want to secure your phone or identify yourself before you enter a building, fingerprint sensors can add security and identification easily. Optical fingerprint sensors or optical scanners have become a common solution to implementing in-display fingerprint scanning. Optical scanners illuminate the fingerprint with a light source, typically a light-emitting diode (LED), and capture the reflected light with a complementary metal-oxide-semiconductor (CMOS) sensor.
