SecuGen SDA04P OEM

SecuGen SDA04P
OEM Fingerprint Module

Compact and durable
Uses SEIR technology
Auto-On™ & Smart Capture™


The SecuGen SDA04P is an OEM grade fingerprint sensor module from SecuGen’s SDA series. The biometric scanner is a standalone system and does not require external computer support. However the module has flexible outputs in the form of RS 232, GPIO and Weigand interfaces for easy integration with other products. The SecuGen SDA04P is available in 3 variants where SDA04P is the standard model, SDA04P-WR is the IP65 standard compliant model and SDA04PIV is the FBI certified variant.

The SecuGen SDA04P produces high speed results by virtue of its inbuilt 1: 1 and 1: N matching algorithm. The module can store up to 10,000 users’ data and has matching and verification speeds less than 0.6 seconds. The module is generally used for security applications such as door locks and identity verification and registration applications.

Special Features

Auto-On™ & Smart Capture™ enabled

The SecuGen SDA04P also uses SecuGen’s Auto-On™ and Smart Capture™ technology. The Auto-On™ technology helps the module scan images automatically when a finger is detected, while Smart Capture™ produces high quality images even when the module is used by dry, aged, wet and scarred fingers.

Uses SEIR optical technology

The Surface Enhanced Irregular Reflection (SEIR) optical technology from SecuGen is a patented technology that strives to produce high quality images different from conventional scanners. The SEIR technology produces image with high contrast and low distortion which makes the matching algorithms produce accurate results.

Compact and durable

One of the biggest factors that determine an OEM grade biometric scanner’s feasibility is its size and sturdiness. The SecuGen SDA04P meets and surpasses expectations in both these cases. The module has a compact size of 21 x 32 x 62 mm which makes it easily integradable in products. It also features an up-gradable IP65 standard compliant variant which makes the module highly durable and maintenance free.
