This product is used by
Obtaining high-quality fingerprint images for:
- Express identity checks against AFIS databases
- Verification of biometric documents
- Access, time and attendance control systems (accelerates the identification process by increasing the number of minutiae recognized in the fingerprint pattern)
The scanner is designed for high-quality electronic fingerprinting.
Its size allows it to be used in access control systems, at security checkpoints, in the work of task force teams and police patrol groups.
For the ‘Prevention of Escapes from Jails and Lock-ups’ Project, a unique system was implemented for simultaneous scanning of two fingers. This increases the number of captured minutiae used for matching, thereby improving the reliability of searches and reducing the total identification time.
Suitable for both indoor and field work:
- Its optical system minimizes the impact of bright light on the image quality
- Housing of the device is made of stainless metal or impact-resistant plastic
- Full fingerprint enrollment of an individual within one minute
The scanner runs under:
- LIVE SCANNER and FILTER software in desktop enrollment and express ID check stations
- GWI (Access, Time & Attendance Control System) software at checkpoints and gateways
- Third-party software with the use of LSSDK
