The perfect fingerprint module for YOU!

The SDU04P fingerprint module is a FIPS 201/PIV compliant single finger capture device that produces highly accurate, high quality fingerprint images.


The design of SecuGen fingerprint sensors is uniquely enforced to enable it to withstand even the harshest of weather conditions. The durability of SecuGen extends to not only its coarse outer surface but its internal hardware and accompanying electronic components as well. Its tough mechanism is tailor-made to deliver excellent performance consistently, without fail or damage.


The accuracy of SecuGen goes unmatched, compared to all its contemporaries due to the elevated optic design. The process of the extraction of data points becomes a breeze due to the distortion-free technology that enhances each image clicked by SecuGen. The experience of using SecuGen is maximized due to its flawless performance every time, delivering precise images, which reduces any chance of false rejection.


Instant authentication is made possible by Auto-On™, which immediately senses whenever a finger is placed on the reader.

High durability and ruggedness

SecuGen is tried and tester to resist deteriorating substances such as dirt, oil and sweat and other harmful impacts such as drops and falls, electrocution, extremely humid and erratic climate and scratches.

Reliable performance

The unfailing ability to perform lets SecuGen power through the most challenging environmental conditions.

Fingerprint data protection

It uses the most advanced software that protects the security of all fingerprint data, making it impossible to hack or reconstruct fingerprint images in anyway.

Ease of integration

Software Developer Kits are available free of cost that enables the smooth integration of into an array of apps.

Device Recognition™

The Device Recognition™ feature enables it to recognize and successfully identify other fingerprint readers in the vicinity.


Unlike any other optical sensors, the sensors embedded inside SecuGen are constructed from a super-strong quartz-like material. This material is known to be immune to things like corrosion, ESD and other impact scratches and breakage. The components that make for the entire optical performance are designed so that they fit like a glove. Hence, there is never any requirement for any additional recalibration even if the optical sensors are briefly lost.


The cost-effectiveness of SecuGen sprouts from the fact that it is designed and assembled in a way that eliminates the need for expensive replacements for a long, long time to come. Its durability and top-notch quality makes it extremely resistant, hence prolonging its life span and ensuring that the system that makes use of it never has to face any downtime, cutting back on a number of potential losses.

Smart Capture™

The Smart Capture™ feature enables it to capture fingerprint images even from the most uneven and unkempt fingertips. It ensures that the quality of the finger print taken from a normal finger is as impeccable as that taken from a scarred, wrinkled, moisture-laden, dry or other more hard-to-scan fingertips.

Patented optical technologies

Patented optical technologies, such as SEIR™ or Surface Enhanced Irregular Reflection, cancel out any chance of image distortion and increase the contrast, accuracy and clarity of the image in the process. It also enhances the signal-noise ratio of the images.

Rejection of false fingerprints

It does not entertain inferior quality latent fingerprints or 2D fingerprint images, often known as photo copies, hence, protecting the authenticity of the fingerprints.

Greater sensor-to-sensor consistency

There is a greater consistency when it comes to sensor-to-sensor accuracy, enabling it to efficiently match fingerprints that are recorded via a number of finger print readers at multiple locations.

Multi-Device Connectivity™

Multi-Device Connectivity™ allows many finger print readers to operate simultaneously, being connected to a single computer that functions as the central controlling device.
