Free Apps to Connect Fingerprint Machines to Odoo

Here are some free community modules (on the Odoo App Store or GitHub) you can use to integrate common fingerprint attendance devices:

1. ZKTeco Attendance Integration

Most common free integration for biometric devices, especially ZKTeco models.

• Module name: zk_attendance (or variations like zkteco_attendance, hr_zk_attendance)
• GitHub link:
  https://github.com/odoo/odoo-addons/tree/13.0/hr_zk_attendance (search for newer forks for v16/v17)
• ✅ Features:
  • Connects to ZKTeco fingerprint devices over IP
  • Downloads attendance logs
  • Maps logs to Odoo hr.employee
  • Generates attendances in hr.attendance

2. AttendHRM Integration (Generic Biometric Devices)

Some modules support AttendHRM-compatible exports (CSV/XML) that can be imported into Odoo.

• Use this if your device doesn’t support direct API/SDK integration.
• Upload logs manually or automate with cron jobs.

3. Biometric Device Sync via Middleware

If the fingerprint device doesn’t support direct integration, use a middleware app to fetch logs and send to Odoo via API (Python script, Node.js, etc.)

• Free Python script: zkpython
  • Supports most ZKTeco models
  • Can be paired with an Odoo custom controller or XML-RPC to sync data

You did not mention the version and any specific machine model. I am assuming Odoo 17. I hope following information will help.

Free Apps for Biometric Integration with Odoo:

hr_zk_attendance Module:
A free app compatible with Odoo 17 for biometric integration. It connects fingerprint machines to Odoo and manages attendance logs.

​Download link: Odoo Apps Store .

Methods to Connect Fingerprint Machines:

1. Install the Module:
2. 1. Download and install the module (e.g., hr_zk_attendance) from the Odoo Apps Store .
3. Configure Device Settings:
4. 1. Add a new biometric device via Attendance > Biometric Device in Odoo .
   2. Adjust the machine’s IP address and port in Odoo to match the device settings .
5. Verify Connection:
6. 1. Test the connection to ensure the device is properly linked to Odoo.
7. Pull and Sync Logs:
8. 1. Use the module’s interface to fetch attendance logs from the device and update Odoo records automatically.

Tips for Smooth Integration:

• Fingerprint Placement: Ensure users position their fingers correctly on the sensor for accurate readings.
• Data Management: Regularly delete old logs or user data from the device to prevent clutter.
• Network Stability: Confirm that the device and Odoo server are on the same network for reliable communication.

Compatibility Check: Verify the module supports your Odoo version (e.g., hr_zk_attendance is for Odoo 17). Please upvote or accept the answer. It helps the community.
