Synaptics Fs7605 Touch Fingerprint Sensor With Pureprint-tm- -

| Feature | Synaptics FS7605 with PurePrint™ | Typical Capacitive Sensor (e.g., FPC, Goodix) | |---------|----------------------------------|------------------------------------------------| | Liveness Detection | On-chip AI (PurePrint™) | None or software-only (slower, less secure) | | Spoof Rejection Rate | >99% | 60–85% (if any) | | Processing Latency | <50ms (full PAD + match) | 100–200ms (external PAD + match) | | Security Certification | ISO 30107-3 compliant | Often none for PAD | | Power Efficiency | <10µA idle, hardware PAD | Higher due to waking CPU for PAD |

: The module communicates over a secured USB interface (commonly matching hardware IDs like USB\VID_06CB&PID_00DF or PID_00F0 ), keeping the communication bus secure against software interlopers. Common System Integrations

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. synaptics fs7605 touch fingerprint sensor with pureprint-tm-

PurePrint™ is an advanced, anti-spoofing technology integrated directly into the sensor's firmware and processing pipeline. Instead of relying solely on a 2D or 3D structural image of the fingerprint, PurePrint™ examines the of the finger. How PurePrint™ Detects Liveness:

The PurePrint™ drivers are regularly updated to recognize and combat new, more sophisticated spoofing techniques as they emerge. SentryPoint™ Integration: It works alongside other tools in the SentryPoint™ security suite Quantum Matcher™ for adaptive template matching and SecureLink™ | Feature | Synaptics FS7605 with PurePrint™ |

is built on the SentryPoint™ security architecture , which includes several layers of defense: their policies apply.

PurePrint™ distinguishes between live human tissue and inanimate spoofing materials by examining:

Beyond its embedded applications, the robust feature set and driver support of the FS7605 have also made it a popular choice for DIY and hobbyist projects. The chip's standard USB interface and the availability of native drivers for both Windows 10 and Windows 11 have led to the creation of customizable USB fingerprint readers based on the FS7605 module. These devices are widely used to add fast and secure Windows Hello authentication to desktop computers or older laptops that lack built-in biometric sensors, breathing new life into older hardware with modern security features.
