Live Finger Detection (LFD) is a technology that detects fake fingerprints copied using rubber, silicone, clay, glue, film, etc. There are two mechanisms for Live Finger Detection. One mechanism is using hardware-based, and another mechanism is using software-based.
Previously, Suprema supported the LFD function only for some devices that support LFD in hardware.
- Available Devices (LFD in hardware): BioStation A2, BioStation L2, BioEntry W2
However, if more customers use the latest BioStar 2 and device firmware to enhance the security of fingerprint authentication, it also supports the function to support software LFD.
You can use the latest features of Suprema through a version upgrade.
* BioStar 2 must match the device model and firmware information.
