SDA04P Description

SDA04P integrates well with door locks and access control units as it has the capability to function without an external Personal Computer(PC). SDA04P is a stand-alone fingerprint recognition system that captures and stores fingerprint data. It is capable of identifying and verifying users registered with an application or security solution. SDA04P is interoperable with data input from SecuGen USB fingerprint readers for varied implementations. It can communicate with external devices quite well. They use next-generation fingerprint technology which uses SecuGen’s fingerprint optic module. This module is very rugged and produces high quality images. It features fast and accurate 1:1 and 1:N search capabilities using SecuGen’s SDKs.

SDA04P-WR features a water resistant optic module suited for integration with IP65-rated products and is SDA04P’s water resistant version.

The perfect OEM fingerprint module for YOU!

SecuGen’s SDA04P OEM fingerprint module is made with the industry’s most rugged and accurate optical sensor based on patented SEIR technology.


SecuGen fingerprint sensors are designed to deliver the best results in different environments. It produces extremely sharp results in Indoor, Outdoor and almost any type of environments. From the external surface to internal lens, these sensors are strong and durable.


The patented optic design lets SecuGen fingerprint sensors to produce distortion-free images making it easier to extract data points for matching purpose. Images produced by these sensors are of high quality providing greater accuracy while reducing the chances of false acceptance.


Auto-On™ helps speed up the reading process. When a finger is placed on the reader, Auto-On™ automatically detects its presence.

High durability and ruggedness

SecuGen fingerprint sensors are designed for the best durability under different circumstances. These sensors are resistant to electrostatic shock, impact, drops, scratches, extreme temperatures and humidity. These sensors are also resistant to contaminants such as sweat, dirt and oil.

Reliable performance

SecuGen fingerprint sensors are designed to deliver reliable performance under challenging conditions and tough environments.

Fingerprint data protection

SecuGen fingerprint sensors come with the Fingerprint data protection technique with templates that capture scratch free fingerprint images.

Ease of integration

It comes with a wide range of free Software Developer Kits that make it easier to integrate these sensors into many types of applications.

Device Recognition™

It comes with a wide range of free Software Developer Kits that make it easier to integrate these sensors into many types of applications.


SecuGen fingerprint sensors are developed using hard quartz like material that makes it resistant to scratches, ESD, Corrosion and many other types of stresses. Its parts are tightly assembled so that even if it is dropped, there will be no impact on its parts.


SecuGen fingerprint sensors are cost effective because SecuGen does everything required to produce good fingerprint sensors. From design to manufacturing, everything is done by SecuGen making its sensors affordable. The best quality material is used to develop the SecuGen fingerprint sensors eliminating the need to replace sensors in short intervals.

Smart Capture™

Thanks to the Smart Capture™ technology used in the SecuGen fingerprint sensors. Because of this technology, SecuGen fingerprint sensors are capable to captures high quality fingerprints from dry, moist, aged, scarred and difficult to-scan fingers for greater accuracy and reliability.

Patented optical technologies

SecuGen fingerprint sensors use Surface Enhanced Irregular Reflection (SEIR™), a patented optical technology that helps producing accurate images that are distortion free with high contrast ad signal-to-noise ratio.

Rejection of false fingerprints

Automatically rejects the false fingerprints like latent prints, 2D fingerprint images, etc. It also rejects photocopies.

Greater sensor-to-sensor consistency

SecuGen fingerprint sensors use greater sensor-to-sensor consistency to ensue highest accuracy when fingerprints collected with different fingerprint readers at different locations are matched.

Multi-Device Connectivity™

Multi-Device Connectivity™ technology makes the SecuGen Sensors versatile. It allows connecting multiple fingerprint readers to one computer at the same time.
