Special Features

Compact and rugged build

The SecuGen SDU04P features a compact build and measures 21 x 32 x 60 mm. The module is built with in-house designed sensors which advocate high quality and low maintenance which gives the module a durable and rugged build.

FBI/FIPS 201 standard images

The SecuGen SDU04P produces 508 DPI and 258 x 336 pixel resolution images that are compliant with FBI standards. The module also features inbuilt 1: 1 and 1: N matching algorithms which when combined with the high data transfer rates of the USB 1.1 and USB 2.0 interfaces produce blazingly fast and accurate results.

Advanced technology

The SecuGen SDU04P uses patented SEIR technology along with Auto-On™ and Smart Capture™ functionalities to provide highly accurate, reliable and power efficient results. The SEIR technology produces high quality high contrast low distortion images, which when combined with Smart Capture™ technology produces best in class results. The Auto-On™ functionality makes the module scan automatically in the presence of a live finger, thus bringing down power consumption levels.
