The FS7605’s defining feature is —a proprietary, hardware-accelerated liveness detection engine that operates on-chip. Traditional fingerprint sensors can be fooled by high-resolution 2D prints (paper, film, silicone) or 3D gelatin molds. PurePrint™ uses machine learning classifiers to analyze minute, subtle differences between live skin and artificial materials.
The capacitive array is tuned to read accurately through minor skin imperfections, such as dry skin, moisture, or slight lotion residue, reducing False Rejection Rates (FRR) while maintaining an incredibly low False Acceptance Rate (FAR). Conclusion
The sensor utilizes advanced capacitive sensing technology to capture a high-resolution 3D ridge and valley pattern of the user’s fingertip. However, where the FS7605 distinguishes itself is not merely in image capture resolution but in its integrated intelligence. synaptics fs7605 touch fingerprint sensor with pureprint-tm-

While high-resolution capacitive sensors can capture incredibly detailed ridge and valley patterns of a fingerprint, standard sensors struggle to differentiate between a real human finger and a high-quality replica. This is where Synaptics’ proprietary technology changes the paradigm. The capacitive array is tuned to read accurately

: Unlike standard sensors that send fingerprint data to the host CPU for verification, this architecture performs all matching and storage directly within the sensor’s dedicated microprocessor. This isolation protects biometric templates from system-level malware or hardware-based attacks on the main operating system. is often part of the , which offers
Example commands:
highlights fast and reliable recognition once the finger is correctly positioned, and high user satisfaction after proper enrollment.
Despite running intensive PurePrint™ liveness checks and cryptographic matching locally on the chip, authentication takes less than 250 milliseconds.
