- Light and mini (thickness of the sensor is only 16mm)
- FBI PIV, Mobile ID FAP20, and STQC certified
- Fingerprint comparison speed is 4 times faster than SLK20M with the same storage capacity
SLK20S is an enhanced version of the SLK20M fingerprint module. It supports a fingerprint acquisition module with a large capacity and a template storage expansion function. Its transmission performance is more stable, and the fingerprint comparison speed is faster than SLK20M.
Integrating with the excellent fingerprint recognition algorithm, ZKFinger V10.0, independently developed by ZKTeco, the product can quickly realize offline extraction and comparison of fingerprint templates on the module, and support fingerprint template comparison on the host.
It provides a complete SDK, supporting the secondary development integration of Windows, Android and Linux systems and fulfilling a variety of adaptation scenarios, such as time & attendance, access control, self-service terminals, and other equipment requiring identity authentication.
- Light and mini (thickness of the sensor is only 16mm)
- Local encrypted storage of 8,000 fingerprint templates
- Offline fingerprint comparison available
- Embedded 2MP CMOS, providing clear and high-quality fingerprint images
- FBI PIV, Mobile ID FAP20, and STQC certified
- Developed based on the Linux operating system, stable and excellent security performance
- Fingerprint comparison speed is 4 times faster than SLK20M with the same storage capacity
