You do not need to download a shady executable. Here is the professional, safe method to use ZKFinger SDK 5.0 in a portable manner.

: Supports both 1:1 (verification) and 1:N (identification) fingerprint matching. Device Compatibility

from pyzkfp import ZKFP2

In the world of biometric security, ZKTeco stands as a behemoth. Their ZKFinger SDK (Software Development Kit) has been the backbone for thousands of developers integrating fingerprint recognition into POS systems, time attendance software, door access controls, and custom authentication apps.

If official download requires membership, there are alternative sources where you can find ZKFinger SDK resources:

Because fingerprint scanners are hardware devices, Windows requires drivers to talk to the USB interface. True portability requires utilizing or extracting the raw driver files ( .inf , .sys , and .cat ) so they can be initialized dynamically or pre-loaded without a full setup wizard. ZKUsbKeep.sys zkfp2.inf 3. Language Bindings / Wrapper DLLs

📌 : Both 32-bit and 64-bit DLL files are provided with the SDK. For 64-bit systems, place 64-bit DLLs in C:\windows\system32 and 32-bit DLLs in C:\windows\syswow64 .

Copy the required DLLs (e.g., from Windows/SysWOW64 for 64-bit systems) directly into your project's bin folder.

In software development, a "portable" SDK or application is one that can run without relying on a traditional Windows installer ( .msi or .exe ).

public void StartPortableScanner()

This command silently installs the local .inf drivers without displaying wizard steps to the user. Using Libusb-Win32 Backend

Integrating ZKFinger SDK 5.0 into your project involves a few key steps: 1. Registering the ActiveX Control

# Perform 1:N identification finger_id, score = zkfp2.DBIdentify(tmp) print(f"Matched user ID: finger_id, Score: score")

Windows 7, 8, 10, and 11 (Both 32-bit and 64-bit architectures).

Prevents issues caused by other software overwriting shared system DLLs.

These components communicate directly with the USB fingerprint reader hardware: zkfpcap.dll Biokey.dll 3. Language and Support Files zkfpeng.dll

// 1. Initialize the SDK Engine int ret = Initialize(); if (ret == 0)

If using ActiveX, you must still register the .ocx file on the target machine using regsvr32 . Downloads and Resources
