The perfect fingerprint device for you!

Advanced LFD technology distinguishes fake fingerprints made from various materials including clay, rubber, silicon, glue, paper, film and more.

1GHz CPU: High Speed Standalone Operation

BioMini Slim 2S is created to be self-sufficient, thanks to its powerful 1.0GHz CPU that allows it to be used for standalone operation. Use of a high frequency CPU enables BioMini Slim 2S to perform on-device fingerprint extraction and matching at exceptional speed.

Fake Fingerprint Detection with LFD Technology

BioMini Slim 2S comes loaded with Suprema’s advanced LFD (Live Finger Detection) technology which allows it to deter fake fingerprint attacks. It can detect fake fingerprints made with material like glue, clay, film, rubber, paper, silicon and more.

Enhanced Security

BioMini Slim 2S uses on-device encryption, which means that fingerprint data is encrypted before it leaves the scanner. Since there will be no unencrypted data on transit between the scanner and connected external device, intercepting it will be futile.

FBI PIV and FBI Mobile ID FAP20 Certificates

BioMini Slim 2S is the world’s thinnest FBI PIV and FBI Mobile ID FAP30 certified optical scanner. It even exceeds the platen size requirement of FAP30 standard with its large 20.32mm x 25.4mm platen size.

HID Protocol Allows True Plug-N-Play

BioMini Slim 2S makes use of HID (human interface device) to support true plug-n-play. True plug-n-play allows users to start using the device (i.e. capturing fingerprints) as soon as they make a physical connection with a compatible device. True Plug-n-Play does not require any installation or setup to use the device.

Multi Dynamic Range (MDR) Technology

Suprema’s extraordinary Multi Dynamic Range (MDR) Technology allows BioMini Slim 3 to capture fingerprints with consistent quality despite harsh lighting conditions. Its image capture quality stays unaffected even in 100,000 LUX ambient lighting, which can be as intense as direct sunlight.

World’s Slimmest FAP 20 Optical Sensor

Fingerprint scanners with optical sensor are often blamed to be bulky but BioMini Slim 2S breaks this perception by using world’s thinnest FAP20 certified optical fingerprint scanner with 13.5mm thickness.
