FxIntegrator - OEM Module (fingerprint recognition)
|
 |
FxIntegrator is a professional module for fingerprint recognition, designed for integration in third party systems. Its high quality fingerprint sensor (top of the market area and resolution) allows to acquire high definition images and to maximize recognition accuracy. The internal powerful microprocessor allows the user identity to be verified in less than 1 second without any additional external hardware. The integration of FxIntegrator into a third party electronic device is very easy thanks to the ICP (Integrator Control Protocol) serial protocol. Moreover, thanks to the ISP (Integrator Simplified Protocol) buttons and led interface, the module can be integrated into third party systems without using external electronics.

The high resolution of the internal sensor (569 dpi; i.e. 69 dpi more than FBI specifications) and its very large sensing area significantly improve the fingerprint recognition accuracy: resolution and area of the FxIntegrator module are the highest among the existing fingerprint modules. Thanks to these features, false rejections due to an incorrect placement of the finger are drastically reduced.

Microprocessor and memory
The core of FxIntegrator is a board equipped with a powerful microprocessor (RISC 32-bit, 200 MHz, ARM9) and 32 MB of RAM. This allows very large images (560×296 pixels) to be processed on-line, without sacrificing recognition accuracy.
Accuracy and efficiency
FxIntegrator can operate both in Verification mode (1:1 match – PIN based), and Identification mode (1:N search on the database of enrolled users) with a very low error rate. A user verification takes about 0.8 seconds.
Template Storage
The FxIntegrator (basic model) can store up to 1500 fingerprints (up to 10000 in the model with max flash memory). Fingerprints are not stored as images but as templates (i.e., compact numerical features extracted from them): from a fingerprint template it is not possible to reconstruct the original fingerprint image.
Integrator Command Protocol (ICP)
FxIntegrator can be driven by third party devices through the serial protocol ICP (Integrator Control Protocol). ICP was designed to interface FxIntegrator with simple 8-bit microcontrollers. FxIntegrator operates as a biometric co-processor and supports storage of fingerprint templates: the external host (master) sends to the FxIntegrator (slave) enrolment, verification, and identifications requests, and wait for a response. Through ICP it is also possible to export/import/delete fingerprint templates and adjust several system parameters.
Integrator Simplified Protocol (ISP)
FxIntegrator can be also interfaced through ISP (Integrator Simplified Protocol). ISP does not require any external host; therefore, integrating the module with other devices through ISP does not require the development of additional electronics. In fact, FxIntegrator is controlled through 3 buttons and few leds: one button for user enrollment; one button for identification over the database of enrolled users, and, finally, one button for canceling the ongoing operation. Once a user has been authenticated a programmable digital output is sent out by FxIntegrator on a specific line.
