CFS flats



Introducing CFS flats—the world’s first highly secure contactless fingerprint scanner.

CFS flats scanner supports 1:N authentication and enrollment via true 3D imaging technology.

Using structured blue light, the compact device captures more than 5 million 3D-points per point cloud and 13 point clouds per second, giving micron-scale resolution. The enhanced accuracy captured by CFS flats scanners is a revolution in contactless fingerprint technology and produces matching scores comparable to current contactless biometric solutions.

CFS flats scanner successfully captures fingerprints in all conditions and functions optimally independent of ambient lighting, motion, skin color variation, and skin moisture levels. The CFS flats scanner simultaneously captures four flat fingerprints significantly faster than contact-based devices (where good contact with the scanning surface is required).

can be used for database enrolment

Resolution down to the micron scale

3D Image capture significantly faster

More than 5 million 3D points

Faster than with contact-based devices



The speed and precision of capture makes CFS flats scanners the ideal solution for a wide range of applications, including airport and border control, access control systems and other public venues where the highest level of security is demanded.

Our Solution


CFS flats

CFS flats, developed by IDloop, is a contactless fingerprint scanner that employs full 3D imaging techniques to capture fingerprints. The CFS flats scanner first projects structured light onto a surface. As the surface is not completely flat, a camera unit detects the distorted linear pattern. Then a computing unit reconstructs a highly detailed 3D point cloud of the microscopic peaks and valleys of the finger.

The process of capturing the surface structure of the hand is extremely fast, with 13-point clouds captured per second, and one-point cloud consists of over 5 million individual data points. This capturing speed achieves a depth resolution of 10 µm.

To simulate a real finger pressing onto a flat surface, the 3D image is converted via an optimized bio-physical model, to a 2D image. This 2D equivalent fingerprint image is ideal for identification, verification, and can be used for database enrolment.

By utilizing our full 3D imaging technology, the peaks and valleys of the fingerprint are clearly differentiable. There is no scale ambiguity, no perspective distortions and only true minutiae.
