: Pre-compiled functions for fingerprint enrollment, matching, and image processing.
The ZKFinger SDK 5.3 is compatible with a wide range of ZKTeco fingerprint scanners, including: For web applications or legacy desktop development, you
Provides development libraries and sample codes for popular programming environments including C++, C#, VB.NET, and Delphi.
The SDK provides APIs for multiple languages:
The 5.3 version is particularly notable for its inclusion of the SLK20R and ZK9500 scanners across all supported operating systems, while older models like ZK4500 and ZK7500 are limited to Windows only.
This allows developers to build robust biometric authentication systems for time attendance, access control, or secure identification applications. The following device families are officially supported: :
The SDK exposes a COM‑based ZKFPEngX class. A typical C# workflow:
Contains the core system .dll and .ocx files required at runtime. Contains USB device drivers for Windows operating systems. Doc
