2.1 About This Guide This document is a developer guide on writing biometrical applications with FFV SDK.
2 Free Fingerprint Verification SDK functionality is based on the high level of accuracy Neurotechnology algorithm which is used in VeriFinger SDK and MegaMatcher SDK.
This software development kit includes a documentation and sample codes for different programming languages that can be used to guide developers to produce their own applications or add a fingerprint biometric functionality to existing applications.
Additionally, FFV SDK enables developers to use a wide range of programming languages in a development environment of their choice to create applications. The FFV SDK is intended to be used in various logon applications, but it can be also used in any other application. FFV SDK supports various fingerprint scanners and it is able to perform a scanned fingerprint verification against another fingerprint stored in an internal database. 1.3 Feedback The information in this guide has been thoroughly reviewed and tested, but if you have noticed errors, omissions or have suggestions for future improvements, please send us feedback via 1ħ 2.2 Additional Resources Free Fingerprint Verification SDK About Neurotechnology 2 Introduction Free Fingerprint Verification software development kit (FFV SDK) is a free software component intended for software developers who want to add fingerprint verification functionality in their own software applications. screenshots, fingerprint images) which can help solve your problem.
