Clockster KIOSK and Biometric Devices
Clockster Kiosk
Clockster Kiosk is Clockster’s proprietary mobile application designed to track employee attendance.
The app can be installed on any Android device and serves as an alternative to biometric terminals — helping companies avoid additional hardware costs.
Key Features of Clockster Kiosk
Records employee clock-ins, clock-outs, and break start/end times
Supports facial recognition for authentication
Sends attendance data to the system in real time
Easy installation via Google Play Market
Clockster Kiosk is a convenient solution for companies that want to manage employee time tracking efficiently — without investing in extra technical resources.
How to Install and Set Up Clockster Kiosk
1. Get Access from Clockster
Before installation, contact our support team to obtain:
Admin login and password for the Kiosk
These credentials are required to sign in and link the device to your company account.
2. Download the Clockster Kiosk App
Open Google Play Market on your Android device and search for Clockster Kiosk,
or use the direct link: Clockster Kiosk on Google Play.
3. Install and Open the App
After installation, launch the app and log in using the provided admin credentials to authorize the device.
4. Place the Device in a Convenient Location
Mount the tablet or smartphone in an easily accessible area (e.g., at the office entrance) so employees can quickly clock in, clock out, and mark breaks.
How Clockster Kiosk Recognizes Employees
Once the Clockster Kiosk app is installed, it must be linked to a specific company location:
Open the admin dashboard.
Go to Settings → Devices.
Link the installed device to the corresponding location where it will be used.
Facial Recognition Requirements
To enable accurate facial recognition, upload a photo of the employee’s face in their profile under Face Photo (Biometric Device).
Photo requirements:
Format: JPEG / JPG / PNG
Minimum resolution: 600×600 px
Background: light and plain
Face: no accessories, no smile, no headwear, no filters
Look directly at the camera, with the face occupying at least 70% of the frame
The photo must be clear, sharp, and in color
Do not upload photos taken from other photos
You can upload the photo directly from the employee’s profile in the admin dashboard.
Important
If your company has multiple locations, each Clockster Kiosk device will recognize only those employees assigned to the same location.
This ensures precise time tracking and access control for each site.
Recommendations for Optimal Use
For improved accuracy, you can set the Recognition Threshold to High in the app settings.
On some Android devices, you may experience issues with face detection (e.g., the face frame not appearing).
This is due to hardware limitations of specific models.
To fix the issue:
In the app settings, change the camera mode from “YUV420” to “NV21”.
This usually resolves detection issues.
⚠️ Note:
YUV420 works reliably on most devices and is set as the default mode.
Switch to NV21 only if you experience problems with the face frame or recognition accuracy.
Biometric Devices
Attendance Tracking
To ensure accurate working hour records, employees must consistently mark their clock-ins and clock-outs.
Clockster offers two ways to register attendance:
1. Clockster Mobile App
Employees can record their arrival, departure, and breaks directly through the Clockster mobile app.
Advantages:
Convenient: employees can mark attendance from their own smartphones.
Flexible: supports geolocation, push notifications, and other features.
No additional equipment required.
Limitations:
Possible errors if employees forget to clock in/out manually.
2. Biometric Devices (Optional)
Clockster also supports integration with select biometric terminals.
These devices can be installed at company locations and automatically register employee arrivals and departures using facial recognition.
Advantages:
Prevents fraudulent clock-ins — the system identifies the actual employee.
Increases discipline and accuracy.
Fully automated — no manual action required from the employee.
Limitations:
Requires purchase and installation of hardware.
May involve maintenance or setup issues (e.g., recognition tuning, connectivity problems).
Devices operate only for employees and locations linked in the system.
📌 Recommendation:
You can use both methods — the mobile app and biometric terminals — depending on your company’s setup.
For example, install terminals at office locations and use the mobile app for remote or field staff.
If you wish to connect biometric devices, please contact our support team to receive a list of compatible models and detailed integration instructions.
Guide: Connecting a Biometric Device in Clockster
Step 1. Device Configuration
When adding a new device, key parameters are entered to enable synchronization with your Clockster admin dashboard.
If you purchased the device through Clockster, it usually comes pre-configured.
If you purchased it independently, request a configuration file from Clockster’s technical support.
Step 2. Device Installation
Once configured, the device must be installed at the designated location where:
There is access to a power source;
For Wi-Fi connection — place it close to the router to ensure a stable signal.
Step 3. Internet Connection
Connect the device to the internet — either via Wi-Fi or Ethernet cable, depending on the model and available options.
Step 4. Linking the Device to a Location
In the Clockster admin dashboard, go to: Settings → Devices, and link the biometric device to the specific location where it’s physically installed.
Step 5. Uploading Employee Photos
All employees working at that location must have a facial photo uploaded to their profiles.
The photo must meet specific quality and angle requirements for proper recognition:
Format: JPEG / JPG / PNG
Minimum resolution: 600×600 px
Background: light, solid color
Face: no accessories, no smile, no headwear, no filters
Look directly at the camera — the face should occupy at least 70% of the frame
Photo must be clear, in color, and not taken from another photo
Step 6. Data Synchronization
After uploading photos and connecting the device to the internet, Clockster will automatically sync employee images to the terminal.
Once synchronization is complete, the device will start recognizing employees by face.
Step 7. Start Using the Device
From this point, employees can clock in and out using the biometric terminal,
and the system will automatically record attendance and calculate working hours according to their assigned schedules.
