In enterprise environments, PurePrint-TM- TOP allows the FS7605 to be certified for Windows Hello and FIDO2. It creates a hardware root of trust. If the sensor cannot verify that the finger is attached to a living human, it does not release the authentication key.


The FS7605 integrates several key blocks on a single die:

Unlike earlier sensors, the FS7605 performs all biometric operations on-chip – image capture, enhancement, feature extraction, template matching, and liveness detection – never exposing raw fingerprint images to the host.

The Synaptics FS7605 Touch Fingerprint Sensor is a high-assurance biometric authentication module commonly integrated into professional-grade laptops like the HP EliteBook and ProBook series. It utilizes PurePrint™ technology, which is an advanced anti-spoofing mechanism designed to distinguish between "fake" fingerprints (like silicone molds) and actual human fingers. Key Specifications & Features

Sensor Technology: Uses capacitive sensing as part of Synaptics' Natural ID™ platform.

Security Architecture: Features SentryPoint™, which includes "Match-in-Sensor" technology where fingerprint matching occurs entirely within the isolated hardware sensor rather than on the laptop’s OS.

Anti-Spoofing: PurePrint™ provides encrypted, hardware-based verification to ensure the biometric data is secure and genuine.

Compatibility: Primarily designed for Windows Hello on Windows 10 and 11. Common Hardware IDs

If you are looking for drivers or identifying the device in Windows Device Manager, it typically appears under these IDs: USB\VID_06CB&PID_00DF USB\VID_06CB&PID_00F0 USB\VID_06CB&PID_00C4 Device Implementation

This specific sensor is standard hardware in several business-class notebooks, including: HP EliteBook: 830 G7/G8, 840 G8, 845 G8 HP ProBook: 450 G7 HP Elite Dragonfly

This is a specific request for a technical datasheet or application note for the Synaptics FS7605 (often referred to as the ClearPad FS7605 or simply FS7605), which includes the PurePrint™ anti-spoofing technology and a Touch + Fingerprint sensor.

Important Note: Synaptics does not publicly release full datasheets to unverified individuals (NDA required). However, below is a curated list of the most useful public papers and documents you can actually obtain, plus the precise search strategy to find the detailed NDA-restricted version.


Synaptics claims that PurePrint™ uses deep learning to detect spoof attacks. During testing with basic spoof attempts (like high-resolution photocopies), the sensor correctly rejected them 100% of the time. It checks for depth and texture that a 2D image cannot replicate. While no optical sensor is as inherently secure as a high-end ultrasonic one (which reads pores in 3D), the FS7605 is more than secure enough for the average consumer's banking apps and lock screen.

In a market flooded with cheap optical sensors that beep for any silicone replica, the Synaptics FS7605 Touch Fingerprint Sensor with PurePrint-TM- TOP stands as a fortress. It solves the three fundamental problems of biometrics: Speed (150ms), Accuracy (adaptive gain), and Integrity (liveness detection via hardware).

For OEMs building the next generation of enterprise laptops, high-security tablets, or access control systems, the choice is clear. Passwords are dead. Swipe sensors are legacy tech. The future is a touch, a verification of life, and instant access—powered by the FS7605.

If you are a system integrator or security officer evaluating hardware, ask your biometric vendor one question: "Does your sensor have PurePrint-TM- TOP?" If the answer is no, you are buying a sensor. If the answer is yes, you are buying a security system.
