ZK Fingerprint Reader Laravel Bridge

A Laravel package to integrate ZKTeco ZKFinger SDK (Biokey.ocx) via a local Windows agent bridge.

⚡ Features

• Enroll, capture, verify, and identify fingerprints using ZKTeco SDK
• Communicates with a local Windows agent (wraps Biokey.ocx)
• Eloquent model for fingerprint templates
• Migration and config publishing

🛠️ Installation

1. Require the package (if published to Packagist):

   composer require yacoubalhaidari/zkfinger-laravel
   

   Or add as a local package in composer.json:

   "repositories": [
     { "type": "path", "url": "packages/zk-fingerprint-reader" }
   ]
   

   Then run:

   composer require yacoubalhaidari/zkfinger-laravel
   

2. Publish config:

   php artisan vendor:publish --tag=zkfinger-config
   

3. Run migration:

   php artisan migrate
   

4. Deploy the local Windows agent (see below).

⚙️ Configuration

Edit config/zkfinger.php as needed. Set the agent URL in your .env:

ZKFINGER_AGENT_URL=http://127.0.0.1:8080

🖥️ Local Windows Agent

You must run a local service on each client machine that wraps the ZKTeco Biokey.ocx ActiveX control and exposes an HTTP API. Example endpoints:

• /enroll (POST)
• /capture (POST)
• /verify/1:1 (POST)
• /identify/1:N (POST)
• /cache/create (POST)
• /cache/add (POST)

See the package documentation or ask for a sample Node.js, Python, or C# agent.

📖 Usage Example

Example controller usage:

use Yacoubalhaidari\ZKFinger\Services\ZKFingerAgentClient;
use Yacoubalhaidari\ZKFinger\Models\FingerprintTemplate;

public function enroll(Request $request, ZKFingerAgentClient $zk) {
    $userId = $request->input('user_id');
    $result = $zk->enroll($userId);
    FingerprintTemplate::create([
        'user_id' => $userId,
        'template_b64' => $result['template_b64'],
        'template_type' => config('zkfinger.template_type'),
        'engine_version' => config('zkfinger.engine_version'),
    ]);
    return response()->json(['status' => 'enrolled']);
}
