The FS7605 is an optical sensor. Unlike ultrasonic sensors (like Qualcomm’s 3D Sonic), which use sound waves to map a fingerprint, optical sensors essentially take a photograph of your finger.
Historically, optical sensors struggled with two things: speed (they were slower than capacitive sensors) and security (a high-res photo could sometimes fool them). This is where PurePrint™ enters the chat.
PurePrint™ is a combination of hardware and AI algorithms designed to distinguish between live skin and spoof materials (like latex, rubber, or printed paper). It uses dynamic pixel optimization to read the unique characteristics of the skin's ridge flow, even if the finger isn't perfectly placed.
