World Class Ultra-slim FAP20 Optical Sensor

SFM Slim is the slimmest 13.5mm FAP20 certified optical fingerprint module
SFM Slim allows you to experience a whole new level of performance that no other has shown so far, featuring 5,000 matches-per-second in max.22,000 templates.

Advanced Live Finger Detection (LFD) Technology

SFM Slim provides advanced Live Finger Detection technology that detects fake fingerprints made of various materials including clay, rubber, silicon, glue, paper, film and more.

Enhanced Security

SFM Slim fingerprint module is designed to provide the highest level of security available by featuring 256-bit AES Fingerprint Data Encryption of fingerprint template data and private key assignment in dedicated memory.

Conformance Decision Engine

Suprema's deep-learning technology applied Conformance Decision Engine(CDE) pre-analyzes fingerprint image before "Pre-processing" step. This CDE enables fingerprint sensor and algorithm's adoptive setting optimization to get the best conditioned fingerprint images even in various condition; dry and wet fingerprint.

FBI PIV and FBI Mobile ID FAP20 Certificates(Image compression standard: WSQ)

SFM Slim is the slimmest FBI PIV and FBI Mobile ID certified fingerprint module. It features a large platen that spans 16.5mm x 21.0mm wide, which is well above the FAP20 Standard (15.2mm x 20.3mm).

Developer-friendly Interface

SFM Slim has multiple interfaces including UART and USB that allow high-speed transfer and a versatile platform compatibility by Android, Linux, Windows SDK
