BioLink SDK

BioLink SDK (Software Development Kit) is a comprehensive full-featured set of programming interfaces and mathematical algorithms that enable developers to implement biometric identification functionality into new and existing solutions. BSDK application programming interface supports C/C++/.NET C#, VB and Delphi.

BSDK is compliant with other BioLink solutions, including all fingerprint scanners of the BioLink U-Match family and automated multi-biometric information system BioLink AMIS.



The BioLink SDK is fully compliant with major industrial standards and can be used for developing applications running on Win32, WinCE and Linux operating systems. The SDK works with the majority of fingerprint scanners with USB and Ethernet interfaces (standalone and embedded models) and comes with a powerful built-in server for ultra-fast processing of fingerprint scans.

BioLink SDK dramatically facilitates the development of applications using fingerprint scanning: authentication systems, POS identification and physical access control systems, time and attendance software and transaction systems of different types. The use of BioLink API allows the developer to focus on the core functionality of the product being developed and save time and effort of building a fingerprint authentication system from ground up.

Key Benefits of BioLink SDK

  • Wide range of supported programming languages and platforms
  • Support for numerous fingerprint scanners with USB and Ethernet interfaces, in both embedded and standalone versions
  • Compliance with international and industry standards
  • Biometric server provider (included into the BSDK package)
  • Graphic interface to obtain and process fingerprint images available in compiled version and source codes
  • Universal low-level API (Application Programming Interface) for consistent operation with various fingerprint scanners
  • Ability to operate both with fingerprints obtained from biometric scanners and their images
  • Support for automated multi-biometric information system BioLink AMIS (for large-scale identification projects)

BSDK covers every aspect of fingerprint-based identification: initial quality control, scan digitization and conversion into a template, fingerprint comparison using one of the two available algorithms, quick adjustment of scanning settings for an optimal quality/performance ratio and fast (de)compression of fingerprints in the WSQ format.
