How to integrate ZKTeco ZK4500 fingerprint scanner with a Django + React web application? [closed]
I'm working on a web application using Django (backend) and React (frontend), and I want to integrate the ZKTeco ZK4500 fingerprint scanner into my system for user authentication.
🔍 My Setup:
- Device: ZKTeco ZK4500 (USB fingerprint scanner)
- Backend: Django (Python)
- Frontend: React (JavaScript)
- OS: Windows 10
📌 What I want to achieve:
- Capture a fingerprint using the ZK4500 from the client machine
- Send the fingerprint data to the Django backend
- Use this data to register or authenticate a user
🧩 The problem: Since this is a web-based application, I understand that I cannot directly access USB devices like the ZK4500 via browser (React). I’m confused about:
- What SDK/library should I use (ZKFinger SDK, BioTime SDK, etc.)?
- How can I create a middleware (Python/C#/Electron) that communicates with the ZK4500 and sends data to Django?
- Is there any existing solution or recommended architecture for this?
🧪 What I’ve tried:
I’ve searched for ZKTeco SDKs and found references to zkemkeeper and ZKFinger SDK for Windows, but most examples are in C# and are designed for desktop applications. I have not found a clear solution for integration with a web-based stack (Django + React).
❓ My questions:
- What is the best approach to use ZK4500 in a web-based system?
- Is there a way to build a bridge app in Python that reads fingerprint data and exposes it via an HTTP API?
- Can you suggest any open-source projects or examples of similar integrations?
Thanks in advance for any guidance or architecture suggestions!
