PurePrint™ is not a software add-on; it is deeply integrated into the sensor’s secure pipeline. The FS7605 conforms to ISO/IEC 30107-3 standards for presentation attack detection (PAD).
Smart home security depends critically on spoof resistance. A $50 smart lock using a cheap sensor can be opened with a photograph. A smart lock using the FS7605 with PurePrint™ can differentiate between a homeowner's finger and a malicious actor's latex copy.
The Synaptics FS7605 represents a significant step forward in consumer biometric security. By embedding PurePrint™ —a hardware-accelerated, AI-driven anti-spoofing engine—directly on the touch fingerprint sensor, Synaptics has created a solution that balances speed, power consumption, and robust presentation attack detection. synaptics fs7605 touch fingerprint sensor with pureprint-tm-
For product designers, the FS7605 is an ideal choice when fingerprint spoofing is a realistic threat model (e.g., financial services, enterprise access, high-value consumer devices). It delivers on the promise of “touch and go” authentication without sacrificing security for convenience—a rare and valuable combination in the world of biometrics.

It is important to note that the FS7605 does not work in isolation. Synaptics bundles the sensor with Synaptics ID (or SID). This is a dedicated system-on-chip (SoC) architecture that stores fingerprint templates in a secure, isolated vault.
This architecture meets the security requirements for Google's StrongBox and Android Keystore, as well as Microsoft's security core PC requirements. Peripheral keyboard manufacturer:
| Pin | Function | |-----|-----------| | 1 | VDD (3.3V) | | 2 | GND | | 3 | USB_DM or SPI_MISO | | 4 | USB_DP or SPI_MOSI | | 5 | SPI_CLK (if used) | | 6 | SPI_CS (if used) | | 7 | RST (reset, active low) | | 8 | INT (interrupt output) |
For most PC integrations, the sensor is soldered to the motherboard or touchpad module – no user wiring needed.
The FS7605 with PurePrint™ targets environments where anti-spoofing is paramount:
