Prerequisites for different Biometric Integration Methods

Introduction

Before you set up biometric device integration with Keka HRMS, it’s important to prepare your system and devices. This ensures a smooth configuration process and minimizes delays during the integration call with our team.

This guide covers:

Minimum system requirements
Standard prerequisites (for SQL, SDK, and Push integrations)
Specific requirements for each integration method (SQL, SDK, Push, API)

Required System Configuration

To run the Keka Sync tool, your system must meet the following minimum requirements:

Operating System: Windows 10
Processor: Intel Pentium 4 or higher
RAM: 4 GB or higher
Disk Space: ~500 GB or higher

Tip: Confirm these specs before scheduling your integration call.

Standard Prerequisites for SQL, SDK, and PUSH Integration Methods

For SQL, SDK, and Push integrations, check the following before proceeding:

All biometric devices are connected to your LAN.
The PC hosting the Keka Sync tool stays powered on and connected to the internet.
Devices show the correct date and time.
Employee attendance numbers in Keka match those in the device.
Device time zone matches office time zone.
If you have a firewall, whitelist:
- Host: a.keka.com
- Ports: 80 / 443
Install Anydesk on the PC for remote support.

Important: Only assign premises to devices after verifying these steps. Doing so too early may trigger incorrect attendance summaries.

Integration Specific Requirements

MS-SQL Based Integration

Currently, only MS-SQL is supported. Please provide the following before your integration call:

Server Name (mandatory)
Database Name (mandatory)
Authentication Type (MS-SQL)
Username
Password
Table Name

Table Structure

The table must include these columns:

Column Name	Data Type	Notes
Device Number	varchar(64) NOT NULL	Biometric device number
User ID	varchar(64) NOT NULL	Employee attendance number
Log Time	datetime NOT NULL	Attendance log entry
Status	varchar(64) NOT NULL	IN/OUT (0=IN, 1=OUT)
Log Index	INT IDENTITY	Log index

There are two setup options:

Single Device Table View:

Table View for Single Device Setup (for both In and Out)

Multi-Device Table View:
Table View for Multiple Devices (for both In and Out)

Push Based Integration

Keep the following ready:

Biometric device images (mandatory)
Device name (optional if image shared)
Model number (optional if image shared)
Serial number (mandatory; Menu → System Info → Device Info)
Device IP address (mandatory; Menu → Comm → Ethernet)

Device Configuration
