Getting started with biometric device integration

Introduction

Keka supports integration with biometric devices such as fingerprint scanners and face recognition systems to track employee attendance and manage secure access.

This article explains the four supported integration methods so you can select the one that best fits your organisation’s needs. Each method has its own advantages, limitations, and prerequisites.

Integration Methods

1. SQL-Based Integration

With SQL-based integration, your biometric device sends attendance data into an MS-SQL database. Keka then reads the data from the database to process attendance.

• Pros:

  • Customizable data flow

  • Reliable and secure storage

  • Works with most SQL-compatible devices

• Cons:

  • Requires SQL knowledge for setup

  • Some devices don’t support SQL export

Note: Keka supports only MS-SQL for this method.

2. SDK-Based Integration

This method uses a Software Development Kit (SDK) from the biometric device manufacturer to connect directly with Keka. It offers real-time data exchange and more control.

• Pros:

  • Deep customization and control over data flow

  • Real-time syncing between device and Keka

• Cons:

  • Requires manufacturer’s SDK (device-specific)

  • More complex to implement

3. Push-Based Integration

Here, the biometric device automatically pushes attendance data to Keka at regular intervals. Once set up, the process is fully automated.

• Pros:

  • Automatic updates with no manual effort

  • Easy to maintain once configured

• Cons:

  • Not all devices support push data

  • Needs a stable network connection

4. API-Based Integration

With API-based integration, the biometric device communicates with Keka through application programming interfaces (APIs). This allows flexible and direct data transfer.

• Pros:

  • Works with a wide variety of devices

  • Enables fast and direct communication

• Cons:

  • May require technical expertise for setup

  • Some older devices may lack API support

Choosing the Right Method

Each integration method has unique strengths:

• SQL: Reliable and adaptable

• SDK: Customizable with real-time updates

• Push: Effortless, automated syncing

• API: Flexible and scalable

Choose based on your device capabilities, IT infrastructure, and organizational needs.

Next Steps

To get started:

1. Decide which biometric device and integration method you want to use.

2. Review the prerequisites for that method. See prerequisites here
