Auto Capture

RealScan SDK's auto capture feature provides automated detection, position check, angle check and image quality check process in real time. It helps users to acquire fingerprint images with a pre-defined quality thereby enabling a seamless & faster live scanning process. RealScan SDK offers both callback method and using SDK functions.



RealScan SDK’s Automatic segmentation is designed to extract multiple fingerprint images from a single slap image. (two-finger & four-finger slaps) it also identifies extracted fingerprint images according to a pre-defined scanning sequence and provides a quality score of each segmented image according to NISTIR 7151 standard.


Sequence Check

Sequence check ensures image quality threshold and accurate allocation of extracted images to the 10-print set. It provides conformity to common

forensic-grade live scanning systems and ensures the integrity of the fingerprint images.

Halo Effect & Ghost

Image Elimination

Using Suprema’s advanced image processing algorithm, RealScan SDK effectively eliminates undesired halo effect* and residual ghost images, therefore it improves the integrity of captured images.

*Halo effect

The effect of condensation from placing warm, moist fingers on the platen.


Slippage & Blurred image Detection

RealScan SDK precisely detects & screens poor quality images and alerts the operator when the image blurs or slips.


* Blurred Image can be caused by excessive pressure on the finger when placing on the prism.

* Slippage occurs mostly during rolled fingerprint capturing.
