Secugen U20-AL USB Fingerprint Reader Module
SecuGen’s highly versatile USB fingerprint sensor modules capture and transmit fingerprint data and can be integrated into a wide range of hardware devices. These compact and durable fingerprint modules are based on SecuGen’s latest, patented fingerprint technology that ensures high quality imaging and accuracy.
The U20-AL features an ultra-compact design and meets FBI Image Quality standards. It is FBI Certified as supporting the PIV, FIPS 201, and Mobile ID FAP 20 specifications.
All models can be integrated with IP54-rated applications that require dust and water resistance and ruggedness for use in tough environments. Ask for the WR version.
