Microprocessor and memory
The core of FxLock 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
FxLock 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.
User Interface
FxLock is equipped with a large back-lighted display (20x4) and a comfortable keyboard which allows the user/administrator to interact with the terminal and control it in a very simple way. Users can be enrolled locally or from a remote computer. |

Power and Environment
FxLock has been designed to be installed in places protected from the direct exposition to sunlight, rain, excessive humidity and dust. Despite FxLock is made of robust components and is quite waterproof, Biometrika does not warrant the use of FxLock for outdoor applications. Temperature should be between 5 and 45 degrees. The unit requires an external power AC (in the range 9 - 12 Volt) or DC (in the range 9 - 24 Volt). The maximum current drawn is 1000 mA |

Fingerprint Sensor
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; the resolution and area of FxLock sensor are the highest among the existing biometric terminals. Thanks to these features, false rejections due to an incorrect placement of the finger are drastically reduced. |

Templates and Transactions Storage
FxLock (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. The terminal can locally store users’ access records. |

Networks and security
FxLock can operate as a complete stand-alone unit (e.g., to control a single door) needing no PC. More FxLock units can be interconnected through a communication network and controlled by one or more Servers (PC). Biometrika can provide ready-to-use software solutions for centralized access control and time&attendance applications (including advanced management of users, groups, gates, permissions, etc.) All the data in transit among the different components of the system are encrypted with state-of-the-art algorithms and dynamic keys (128 bits).
The FxLock units can be interconnected (network) through RS 232, RS 485 or Ethernet. |
