.ZK Finger SDK currently supports Windows 9x/2000/NT and Linux OS Platforms. Under Windows environment, the SDK comes in both DLL and ActiveX formats. For Linux environment, the relevant drivers and files are provided. ZK Finger SDK is an extremely powerful tool that provides system integrators ease of interface. As long as the image is obtainable, the SDK will be able to extract fingerprint templates from any type of sensors. The images can be from Bitmap in memory or taken from various image files in BMP, JPG, TIFF, GIF formats with 256 grey scale levels. It can do automatic classification of fingerprints and conduct 1 - M identification matches of up to 10,000 per second.

ZK Finger SDK Powerful Features:

1. Ability to extract minutia through fingerprint images, and files. The size of the file is about 256 bytes to about 1024 bytes depending on the extraction method. There are 3 types of extraction method: fingerprint images, bitmap file handle, and two-dimensional byte array.

2. The enrolled or registered fingerprint template can be obtained by 1 - 3 repeated placements of the fingers on the sensor; the size of the enrolled templates varies between 256 or 1024 bytes

3. Allows 1:1Verification capability with a stored fingerprint template.

4. Makes use of the DRAM memory for 1: N Matching. Normally, all the stored templates are buffered into the RAM memory for quick 1: N Matching.

5. ZK Finger SDK currently supports many OS platforms, for development purposes, sample source codes in Visual C++ 6.0, C++ Builder 5.0, Viusal Basic 6.0, Delphi 5.0 are provided, the use of (DLL) and ActiveX components are all demonstrated using the ZK Finger SDK program samples.

ZK Finger SDK is protected by a dongle. However, that same dongle can also be used for the protection of other software developed by the System Integrator themselves.
