The Fx2100 fingerprint scanner (completely designed and developed by Biometrika) fills the large gap existing between the expensive high-quality scanners (FBI-compliant) and the entry-level systems (which do not allow robust and reliable applications to be developed). In fact, the high resolution certified by FBI according to PIV (Personal Identity Verification) Image Quality Specifications and the large sensing area of the Fx2100 scanner allow the acquisition of good quality images and a drastic reduction in the percentage of false rejections. Thanks to its powerful 32-bit Risc CPU the scanner performs directly several operations related to security; in particular, state-of-the-art encryption (128-bit) of all the information exchanged between the scanner and the PC is provided.

These features have to be carefully considered when evaluating the quality of a fingerprint scanner. In fact, a large sensing area improves recognition performance since a larger number of minutiae can be detected (see minutiae) and the overlapping area of two fingerprint images, taken in different moments, is significantly maximized. This increases the overall accuracy (smaller FAR) and, above all, greatly reduces the false rejections (FRR) caused by incorrect finger placements. Furthermore, the higher is the resolution, the more details can be located in the fingerprint pattern.
The pictures on the right show, at the same scale, two images from the same finger: one captured by Fx2100 (on the left: 560x296 pixel, 569 dpi) and one by a typical solid-state capacitive scanner (on the right: 96x96 pixel, 250 dpi).
Fx2100 can operate an autonomous detection of the finger presence on the sensor platen, without charging the CPU of the connected PC. A green, blinking led indicates that the autodetection is on.
All the information in transit between the scanner and the PC are encrypted. Fx2100 implements some encryption algorithms and can follow several distinct procedures negotiated with the PC at the initialization time. 128-bit "state of the art" symmetric algorithms are used together with non-repeatable keys, to secure the communications with the PC.
At initialization time a negotiation occurs between the scanner and the PC to set the desired encryption mode. To do so, the user must press the small button at the back of the scanner to prevent any "unwanted" attempt to reset the encryption mode.
Live showing the captured images is a valid help at acquisition time to better adjust the finger position and pressure. However, showing fingerprint patterns in "clear" on the screen can be dangerous from a security point of view, since:
Fx2100 provides an excellent solution to this problem: the “blind” mode. The scanner computes in hardware the silhouette and the contrast of the fingerprint image and sends them to the PC for real-time presentation.
Fx2100 is available with USB 2.0 interface.
USB version: Windows 98/2000/XP/Vista/7, Linux
The Fx2100 scanner is available also as SC version (with an integrated Smart Card reader). The reader is detected by the Operating System as a standard PC/SC device and can be used by every application (third party also) to read/write most of the existing Smart Cards and Memory Cards. Fx2100 SC is a very cost-effective solution for applications requiring to store biometric templates on Smart Cards released to the users (max. privacy), and in secure applications of Digital Signature.
Fx2100 SC is compliant with Windows and Linux operating systems.
Fx2100 is available also as OEM version (without the external cover); the OEM scanner is suitable for integrations in third party devices. However, Fx2100 OEM is not a stand-alone system and therefore requires a PC running the recognition software.
Fx2100 driver also provides a TWAIN interface that enables the acquisition of fingerprint images through any software that supports this standard interface. Once installed, Fx2100 can be selected as a TWAIN image source from any application that supports the TWAIN interface.
